1. Factorise.
a. 6x + 4x² – 2x b. x + x + x + x²
2. Factorise using identities.
a. 9a2 + 42ab + 4962 b. 4x2 – 36xy + 8132​

Answer 1

Answer:

1 =

$6x \times 2x = {12}^{2}$

$12{x}^{2} = 2 \times 6 = 12> 1 \times 12 = 12$

$6x + 4 {x}^{2} - 2x$

$6 - 2 = 4$

$6x + 6 x + 2x - 2x = 0 \\ \\ 6x( 1+ 1) + 2x(1+ 1) = 0$
