Question

Factorise 12a^2+2a-4​

Answer 1

SOLUTION

$= > 12 {a}^{2} + 2a - 4 \\ = > {12a}^{2} + 8a -6a - 4 \\ = > 2a(6a + 4) - 6(6a + 4) \\ = > (6a + 4) \: \: (2a - 6)$

hope it helps ☺️

Answer 2

Answer:

We have

12a^2 +2a-4

We can write

12a^2 +8a-6a-4

2a(6a+4)-1(6a+4)

Now

(2a-1) and (6a+4)

These are the factors of this equation
