Answer:
x=2 x=-4
Step-by-step explanation:
x^2 +2x-8=0
Factor
What numbers multiply to -8 and add to 2
-2*4 = -8
-2+4 =2
(x-2) (x+4) =0
Using the zero product property
x-2 =0 x+4 =0
x-2+2=0+2 x+4-4=0-4
x=2 x=-4
Answer:
[tex]x = -4, x = 2[/tex]
Step-by-step explanation:
Step 1: Factor
[tex]x^2 + 2x - 8 = 0[/tex]
[tex]x^2 + 4x - 2x - 8 = 0[/tex]
[tex](x + 4)(x - 2) = 0[/tex]
Step 2: Find the zeros
[tex]x + 4 - 4 = 0 - 4[/tex]
[tex]x = -4[/tex]
[tex]x - 2 + 2 = 0 + 2[/tex]
[tex]x = 2[/tex]
Answer: [tex]x = -4, x = 2[/tex]
