Answer:

[tex]x = -7, x = 4[/tex]

Step-by-step explanation:

Step 1:  Solve for x

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

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

[tex]x = -7[/tex]

[tex]x - 4 = 0[/tex]

[tex]x - 4 + 4 = 0 + 4[/tex]

[tex]x = 4[/tex]

Answer:  [tex]x = -7, x = 4[/tex]

I'll teach you how to solve (x + 7)(x - 4) = 0

-------------------------------------------------

(x + 7)(x - 4) = 0

Use the zero factor principle:

Solve x+7=0:

x+7=0 = x=-7

Solve x-4=0:

x-4=0 = x=4

The solutions are:

x=-7, x=4

Your Answer Is x=-7, x=4

plz mark me as brainliest :)
