MCQ
$(4x^2 + 4x - 3) = ?$
- A$(2x - 1) (2x - 3)$
- BNone of these.
- ✓($2x + 3) (2x - 1)$
- D$(2x + 1) (2x - 3)$
✓
Answer
Correct option: C.
($2x + 3) (2x - 1)$
$(4x^2) + (4x - 3) = 4x^2 + 6x - 2x - 3$
$= 2x(2x + 3) - 1(2x + 3)$
$= (2x + 3) (2x - 1)$
$= 2x(2x + 3) - 1(2x + 3)$
$= (2x + 3) (2x - 1)$
