Question

(x²+7x+12) factorise the question​

Answer 1

Answer:

x² + 4x + 3x + 12

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

( x +3 )( x+ 4)

the therefore

x = -3

or d = -4

Answer 2

Answer:

$(x-3)(x-4)$

Step-by-step explanation:

We are looking for factors of 12 which ADD (because of + 12) up to 7.

The signs will be the same (because of + 12), they are both negative (because of -7).

The factors which satisfy both conditions are  $-3$ and $-4$

− 3 × − 4 = + 12

, and − 3 + − 4 = − 7

$(x-3)(x-4)$
