Question

Find the solution
x²+6x + 8 = 0
​

Answer 1

Answer:

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

Answer 2

Step-by-step explanation:

x^2+6x+8=0

x^2+6x=-8

x(x+6)=-8

x+6=-8/x

6=-8/x-x

6=-8-x^2

-14=x^2

x=-3.74
