Question

please give answer of this question​

Answer 1

Step-by-step explanation:

$4 {x}^{2} + 8x + 3 \\ 4 {x}^{2} + 2x + 6x + 3 \\ 2x(2x + 1) + 3(2x + 1) \\ (2x + 1)(2x + 3)$

Answer 2

4x² + 8x + 3

4x² + 6x + 2x + 3   (splitting up of middle term)

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

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

(2x+3) = 0  or  (2x+1) = 0

x = -3/2 or x = -1/2
