Answer:

x=4, -7

Explanation:

4 (x−4)(x+7)=0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

x−4=0x+7=0Set x−4 equal to 0 and solve for x. Set

x+7 equal to 0.x+7=0

Subtract 7 from both sides of the equation. x=−7

The final solution is all the values that make 4(x−4)(x+7)=0 true.

x=4,−7
