Steps-
First, distribute within the parenthesis: 8x+40=0
Subtract 40 from both sides: 8x=-40
Divide both sides by 8: x=-5
Answer: x=-5

4(2x + 10) = 0
Distribute: 8x + 40 = 0.
Subtract 40 from both sides of the equation ==> 8x = -40
Divide by 8: x = -5

Substitute back into the equation to check.
4(2(-5) + 10) = 0
4(-10 + 10) = 0
4(0) = 0
0 = 0

x is equal to -5.
