Question

Resolve into factors :
x^2+4x+3x+12​

Answer 1

Answer:

(x+4)(x+3)

Step-by-step explanation:

= x^2+4x+3x+12

= x(x+4)+3(x+4)

= (x+4)(x+3).

Answer 2

Step-by-step explanation:

${x}^{2} + 4x + 3x + 12$

$x(x + 4) + 3(x + 4)$

$(x + 4)(x + 3)$

$if \: x + 4 = 0$

$x = - 4$

$if \: x + 3 = 0$

$x = - 3$
