Q19) Factorise 5(x + 2)^2 + 7(x + 2) - 6 *​

Answer 1

Answer:

$= 5 {(x + 2)}^{2} + 7(x + 2) - 6 \\ = 5 {(x + 2)}^{2} + 10(x + 2) - 3(x + 2) - 6 \\ = 5(x + 2)(x + 2 + 2) - 3(x + 2 + 2) \\ = 5(x + 2)(x + 4) - 3(x + 4) \\ = (x + 4)(5)(x + 2 - 3) \\ = 5(x + 4)(x - 1)$

Answer 2

it is a easy way to solve that sum
