Question

Which of the following is the factored form of the quadratic *

12x^2+5x-2=0

1.(4x - 1)(3x - 2)
2.(4x - 1)(3x + 2)
3.(4x + 1)(3x - 2)

Answer 1

2

Explanation:

`12x^2+5x-2=\\\\(4x-1)(3x+2)`

You can check this by working backwards and expanding:

`(4x-1)(3x+2)=\\\\12x^2-3x+8x-2=\\\\12x^2+5x-2`

Hope this helps!
