Answer:

x= -7      x = -1

Step-by-step explanation:

x^2 + 8x + 7 = 0

Factor

What 2 numbers multiply to 7 and add to 8

7*1 = 7

7+1 = 8

(x+7)(x+1) =0

Using the zero product property

x+7 =0   x+1 = 0

x= -7      x = -1

Answer:

[tex]x = - 1 \\ x = - 7[/tex]

Answer B is correct

Step-by-step explanation:

[tex] {x}^{2} + 8x + 7 = 0\\ {x}^{2} + 7x + x + 7 = 0\\ x(x + 7) + 1(x + 7) = 0 \\ (x + 1)(x + 7) = 0[/tex]

[tex]x + 1 = 0 \\ x = - 1[/tex]

[tex]x + 7 = 0 \\ x = - 7[/tex]

hope this helps
