Solve the equation. 4x2 – 8 = 56

2, –2
16, –16
8, –8
4, –4

4,-4

Step-by-step explanation:

4x2-8=56 is our equation.

First we add 8 on both sides to get rid of the "-8" on our equation,we do it on both sides because when you do something on one side of an equation you have to do it on the other.That will leave us with: 4x2=64So we will solve our exponent: 4x2Then we will have: 16x=64 because 4 times 4 is 16Then we will divide by 16 on both sides to get rid of "16" in "16x"That will leave us with: x=4 for our answer! :>I hope this helped.And please give me brainliest.I am trying to get more brainliest.Thank you!
