Question

Factorise:- 2x²+7x+3

Answer 1

Answer:

$- \frac{1}{2} \: or \: - 3$

Step-by-step explanation:

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

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

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

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

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

Answer 2

Answer:

$2 {x}^{2} + 7x + 3 \\ = 2 {x}^{2} + (6 + 1)x + 3 \\ = 2 {x}^{2} + 6x + x + 3 \\ = 2x(x + 3) + 1(x + 3) \\ = (x + 3)(2x + 1)$

Therrfore,

Either, Or,

x= -3. x= -1/2
