Polynomials – Important Notes

• Polynomials have variables, constants, and whole number exponents.
• The zeroes of a polynomial are the values of x where the polynomial becomes zero.
• The relationship between coefficients and zeroes helps in solving problems quickly.
• The division algorithm helps break polynomials into quotient and remainder.
• Factorisation makes solving equations easy.
• Identities are useful shortcuts in algebra.

Types of Polynomials

Polynomials are classified based on degree (highest power of xxx) and the number of terms.

(A) Based on the Number of Terms

Monomial – Has only one term.

Example: 5x, 3xy, −7a³

Binomial – Has two terms.

Example: x+5, 4x²−3y 

Trinomial – Has three terms.

Example: x²+3x+2, a³−4a+7

(B) Based on the Degree (Highest Power of the Variable)

Constant Polynomial – No variable, only a number.

Example: 5, −3, 8

Linear Polynomial – Highest power of x is 1

Example: x+2, 3y−4

Quadratic Polynomial – Highest power of x is 2

Example: x²+5x+6

Cubic Polynomial – Highest power of x is 3

Example: x³−4x+7

 Zeroes of a Polynomial

• The zeroes of a polynomial are the values of x for which the polynomial becomes zero.
• If p(x) is a polynomial, then its zeroes satisfy:

p(x)=0

Example:

For p(x)=x²−4

x²−4=0

⇒(x−2)(x+2)=0

So, the zeroes are x=2 and x=−2.

Relationship Between Coefficients and Zeroes

For a quadratic polynomial ax²+bx+c

Sum of zeroes = −b/a

Product of zeroes = c/a

Example:

For x²−5x+6

• Zeroes are 2 and 3(because (x−2)(x−3)=0
• Sum of zeroes = 2+3=5
• Product of zeroes = 2×3=6

Similarly, for cubic polynomials,

• Sum of zeroes = −b/a
• Sum of product of zeroes (taken two at a time) = c/a
• Product of zeroes = −d/a​

Division Algorithm for Polynomials

For any two polynomials p(x) and g(x),

p(x)=g(x)×q(x)+r(x)

where,

• p(x) = Dividend (Polynomial to be divided)
• g(x) = Divisor (Polynomial by which we divide)
• q(x) = Quotient (Result of division)
• r(x) = Remainder (Leftover part after division)

Example:

Dividing x³−3x²+5x−3 by x−1:

Quotient = x²−2x+3

• Remainder = 000

This means,

(x³−3x²+5x−3)=(x−1)(x²−2x+3)

Factorisation of Polynomials

Factorisation means breaking a polynomial into simpler polynomials (factors).

Methods to Factorise:

By taking common factors

Example: 2x²+4x=2x(x+2)

By splitting the middle term

Example: x²+5x+6=(x+2)(x+3)

Using identities

a²−b²=(a−b)(a+b)

a³−b³=(a−b)(a²+ab+b²)

a³+b³=(a+b)(a²−ab+b²)

Important Polynomial Identities

These identities help in factorisation and simplification:

• (a+b)²=a²+2ab+b²
• (a−b)²=a²−2ab+b²
• a²−b²=(a−b)(a+b)
• (x+a)(x+b)=x²+(a+b)x+ab
• a³−b³=(a−b)(a²+ab+b²)
• a³+b³=(a+b)(a²−ab+b²)

Graphical Representation of Polynomials

• A linear polynomial (ax+b) represents a straight line.
• A quadratic polynomial (ax²+bx+c) represents a parabola (U-shaped curve).
• The points where the curve touches the x-axis are the zeroes of the polynomial.

Common Mistakes Students Make in Polynomials (Class 10 Maths)

Understanding polynomials is easy, but many students make avoidable mistakes on exams. Here are some of the most common ones and how to avoid them:

Confusing Zeroes with Coefficients

Mistake: Thinking the zeroes of a polynomial are the same as its coefficients.

Correction: The zeroes of a polynomial are the values of x that make the polynomial zero (i.e., roots of the equation p(x)=0, not the coefficients.

Example:

For x²−5x+6, the coefficients are 1, -5, and 6, but the zeroes are 2 and 3 because:

(x−2)(x−3)=0

Incorrect Application of Sum and Product of Roots Formula

Mistake: Getting the wrong signs in the sum and product of roots formula.

Correction: Always remember the formulas correctly for a quadratic polynomial ax²+bx+c:

Sum of zeroes = −b/a

Product of zeroes = c/a

Example:

For 2x²−7x+3

Sum of zeroes = −(−7/2)

=7/2  (NOT -7/2)

Product of zeroes = 3/2

Forgetting That a Polynomial’s Degree Must Be a Whole Number

Mistake: Writing expressions like x⁻²+4 or 3x+(1/x) as polynomials.

Correction: A polynomial’s exponent must always be a whole number (0, 1, 2, 3, etc.). If an exponent is negative or a fraction, the expression is not a polynomial.

Ignoring the Remainder in Polynomial Division

Mistake: Assuming that every polynomial division results in a quotient with no remainder.

Correction: Always check if a remainder exists when dividing polynomials. The division algorithm states:

p(x)=g(x)×q(x)+r(x)

where r(x) is the remainder.

If r(x)≠0, the divisor is not a factor of the polynomial.

Mistakes in Factorisation

Mistake: Incorrectly splitting the middle term while factorising quadratic polynomials.

Correction: Always check that the two numbers you use for factorisation multiply to give the constant term and add to give the middle coefficient.

Example:

Factorise x²+7x+12.

Correct: (x+3)(x+4) because 3×4=12 and 3+4=7

Incorrect: (x+2)(x+6) because 2×6=12 but 2+6≠72.

Forgetting Important Algebraic Identities

Mistake: Misapplying or forgetting identities when solving polynomial problems.

Correction: Memorise and practise the following identities:

• (a+b)²=a²+2ab+b²
• (a−b)²=a²−2ab+b²
• a²−b²=(a−b)(a+b)
• (x+a)(x+b)=x²+(a+b)x+ab
• a³−b³=(a−b)(a²+ab+b²)
• a³+b³=(a+b)(a²−ab+b²)

If you don’t apply these correctly, you’ll make mistakes in factorisation and simplification.

Graphical Representation Errors

Mistake: Incorrectly plotting the graph of a quadratic polynomial.

Correction: Remember:

• A linear polynomial (ax+b) is a straight line.
• A quadratic polynomial (ax²+bx+c) forms a parabola (U-shaped curve).
• The x-intercepts (where the curve touches the x-axis) are the zeroes of the polynomial.

Ignoring the Leading Coefficient in Polynomials

Mistake: Forgetting that a polynomial’s leading coefficient affects its shape and nature.

Correction:

• If the leading coefficient is positive, a quadratic polynomial opens upwards.
• If the leading coefficient is negative, it opens downward.

Example:

• x²−4x+3 → U-shaped (opens upwards)
• −x²+4x−3 → ∩-shaped (opens downwards)

Forgetting to Check the Final Answer

Mistake: Rushing through calculations and getting incorrect zeroes or factors.

Correction: Always substitute your answers back into the polynomial to verify.

Example:

If you find the zeroes of x²−5x+6 to be x=2,3, check:

(2)²−5(2)+6=4−10+6=0

(3)²−5(3)+6=9−15+6=0

Skipping Steps in Polynomial Division

Mistake: Writing the quotient directly without properly dividing step by step.

Correction: Polynomial division is similar to long division. Write each step carefully to avoid mistakes.

How to Avoid These Mistakes?

Practise regularly – The more you practise, the fewer errors you'll make.

Double-check calculations – Go through your steps carefully, especially in exams.

Understand concepts – Don’t just memorise; make sure you understand the logic behind formulas and methods.

Use rough work – Write calculations clearly so you don’t skip steps or get confused.
