Question

Factorise it
((X+2)^2)-((x+4)^2)

Answer 1

Answer:

x =-3

Step-by-step explanation:

Given:-

${(x + 2)}^{2} - {(x + 4)}^{2} \\ \\ now \: we \: can \: use \: identities \: here \\ \\ {x }^{2} - {y}^{2} = (x + y)(x - y) \\ \\ \\ (x + 2 + x + 4)(x + 2 - (x + 4) \\ \\ (2x + 6)( - 2) \\ \\ - 4x - 12 = 0 \\ \\ - 4x = 12 \\ x = \frac{12}{ - 4} \\ \\ x = - 3$
