Answer:
x=-2 OR x=-4
Step-by-step explanation:
Step 1: Subtract -6x from both sides.
x2+8−−6x=−6x−−6x
x2+6x+8=0
Step 2: Factor left side of equation.
(x+2)(x+4)=0
Step 3: Set factors equal to 0.
x+2=0 or x+4=0
x=−2 or x=−4
Good luck! Hope this helps!
Step-by-step explanation:
[tex] {x}^{2} + 8 - ( - 6x) = 0 \\ x {}^{2} + 8 + 6x= 0 \\ x { }^{2} + 6x + 8 = 0 \\ x {}^{2} + 4x + 2x + 8 = 0 \\ x(x + 4) + 2(x + 4) = 0 \\ (x + 4)(x + 2) = 0 \\ either \\ x + 4 = 0 \\ x = - 4 \\ or \\ x + 2 = 0 \\ x = - 2 \\ hence. \\ x = - 4and - 2[/tex]
