CBSE Class 9 (Maths) - Polynomials - Exercise 2.4

Factor Theorem


1. Let p(x) be a polynomial and a be any real number. If p(a) = 0, then (x–a) is a factor of p(x).

2. If (x–a) is a factor of p(x), then p(a) = 0

EXERCISE 2.4 (NCERT Solution)

Q1: Determine which of the following polynomials has (x + 1) a factor :
(i) x3 + x2 + x + 1
(ii) x4 + x3 + x2 + x + 1
(iii) x4 + 3x3 + 3x2 + x + 1
(iv) x3 – x2 – (2 + √2)x + √2

Answer: If (x+1) is a factor of a polynomial p(x), then p(-1) must be equal to zero.
