I am trying to find the answer to this problem but I'm doing something wrong, and I can't figure out what mistake I'm making.
Here's the problem:
(-2)²-2(-2)3+3²
First I got rid of exponents:
4-2(-2)3+9
Then I multiplied:
4-12+9
Last, I added and subtracted:
4-12+9=1
But here's the problem, 1 is not the answer, 25 is the answer, but I have no idea how someone would get 25. What am I doing wrong?
