RS Aggarwal Solutions Class 8 Mathematics Solutions for Factorisation Exercise 7E in Chapter 7 - Factorisation

Question 2 Factorisation Exercise 7E

$\left(2x-32x^3\right)=?$

a. 2(x-4)(x+4

$\text{ b. }2x(1-2x)^2$

$\text{ c. }2x(1+2x)^2$

d. 2x(1-4x)(1+4x)

Answer:

let us consider $\left(2 x-32 x^{3}\right)=2 x\left(1-16 x^{2}\right)$ by taking 2x as the common factor

By using the formula $a^{2}-b^{2}=(a-b)(a+b)$

= 2x (1 – 4x) (1 + 4x)
