Question

Factorise each of the following: (x + 2)² – (x + 4)² using identites proper solution​

Answer 1

Answer:

(-4) , (x + 3)

Step-by-step explanation:

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

(a + b)2 = a2 + 2.a.b + b2

[(x)2 + 2.x.2 + (2)2] - [(x)2 + 2.x.4 + (4)2]

[x2 + 4x + 4] - [x2 + 8x + 16]

x2 + 4x + 4 - x2 - 8x - 16. [ x2 se x2 cut]

- 4x - 12

-4 (x + 3)

-4 , x + 3
