MCQ
The factors of $12 x^2-x-6$ are:
- ✓$(3x + 2) (4x - 3)$
- B$(12x - 1) (x + 6)$
- C$(3x - 2) (4x + 3)$
- D$(12x + 1) (x - 6)$
✓
Answer
Correct option: A.
$(3x + 2) (4x - 3)$
$12 x^2-x-6$
$=12 x^2-9 x+8 x-6$
$=3 x(4 x-3)+2(4 x-3)$
$=(3 x+2)(4 x-3)$
$=12 x^2-9 x+8 x-6$
$=3 x(4 x-3)+2(4 x-3)$
$=(3 x+2)(4 x-3)$
