Question

factorise the following
(x + 2)² - (x + 4)²​

Answer 1

Answer:

$4x - 8x = x = 2$

Answer 2

Answer:

Step-by-step explanation:

Given,

(x + 2)^2 - (x + 4)^2

= (x^2 + 2^2 + 2 × x × 2) - (x^2 + 4^2 + 2 × x × 4)

= (x^2 + 4 + 4x) - (x^2 + 16 + 8x )

= x^2 + 4 + 4x - x^2 - 16 - 8x

= - 4x - 12 or -4 ( x + 3) is the answer
