Your answer would be -43

____________________________________________________

Explanation:

To solve this problem, we would need to plug in the number "5" in x.

Therefore, your equation should look like this:

`-2(5)^2+2(5)-3`

First, you would need to solve the exponent, making it equivalent to 5 × 5, then you can solve with ease.

`-2(5)^2+2(5)-3\\\\-2(25)+2(5)-3\\\\-50+10-3\\\\=-43`

All we did when we solved this was plug in and solve, that's really the only thing you need to do in questions like this.

When you're done solving, you should get the answer -43.

-43 would be your FINAL answer.
