Expand with suitable identity 2x²+7x+3

$\huge\bigstar\huge\tt\underline\red{ᴀɴsᴡᴇʀ }\bigstar$

$2 {x}^{2} + 7x + 3$

$2 {x}^{2} + 6x + x + 3$

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

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

$x = - \frac{1}{2} \: and \: x = - 3$

Hope it helps you..!!!

Answer 2

Answer:

2x² + 6x+ x +3 = 0

2x ( x + 3) + 1 ( x+3) = 0

(2x +1) , (x+3) = 0

x = -1/2 , x= -3
