Question

Factorize by sing suitable identity

Answer 1

Given;

• (x+1)² - 8(x+1) + 16
• let (x+1) = A

Then the expression would be;

• A² - 8A + 16
• (A)² - 2(4A) + (4)²

using (a-b)² = a² - 2ab + b²

The expression would be ;

• (A-4)²
• (A-4)(A-4)

(substitute value of A )

• (x + 1- 4)(x + 1- 4).
• (x - 3)(x - 3)
