Question

Factories 3-12(a-b)^2​

Answer 1

Step-by-step explanation:

$3 - 12 {(a - b)}^{2} \\ = 3[1 - 4 {(a - b)}^{2}]\\ = 3[{(1)}^{2} - {{[2(a - b)]}}^{2} ] \\ = {x}^{2} - {y}^{2} \\ = (x + y)(x - y) \\ = 3(1 + 2a - 2b)(1 - 2a + 2b)$

$$\begin{lgathered}3 - 12 {(a - b)}^{2} \\ = 3[1 - 4 {(a - b)}^{2}]\\ = 3[{(1)}^{2} - {{[2(a - b)]}}^{2} ] \\ = {x}^{2} - {y}^{2} \\ = (x + y)(x - y) \\ = 3(1 + 2a - 2b)(1 - 2a + 2b)\end{lgathered}$$
