The factorisation of 4x^2 + 8x + 3 is: - Vidyadip

MCQ

The factorisation of $4x^2 + 8x + 3 $ is:

A
$(2x - 1) (2x - 3)$
B
$(x + 1) (x + 3)$
✓
$(2x + 1) (2x + 3)$
D
$(2x + 2) (2x + 5)$

✓

Answer

Correct option: C.

$(2x + 1) (2x + 3)$

Now, $4x^2 + 8x + 3 = 4x^2 + 6x + 2x + 3 [$by splitting middle term$]$
$= 2x(2x + 3) + 1(2x + 3)$
$= (2x + 3) (2x + 1)$
