Question

Factorise: xsquare + 6x + 8​

Answer 1

Answer:

$x {}^{2} + 6x + 8 = 0 \\ = x {}^{2} + 4x + 2x + 8 = 0 \\ = x(x + 4) + 2(x + 4) = 0 \\ = (x + 4)(x + 2) = 0 \\ x = - 4 \: \: and \: \: - 2$

Here is your solution

Answer 2

Step-by-step explanation:

x^2 + 6x +8

x^2 + 4x + 2x +8

x(x+ 4) + 2(x + 4)

(x + 4) (x + 2)=0

x= -4 , -2
