Just do the operations. The first step would be to rewrite it as
3 -81 -36 +8 -2
and then add up terms
I assume you meant 3 - 9^2 and not (3-9)^2 at the beginning. If you meant (3-9)^2, the answer is
36 -36 +8 -2 = 6
3-9^2 - 4(3)^2 + 8 - 2 how do you solve this?
2 answers
3-9^2 - 4(3)^2 + 8 - 2
= 3 - 81 - 36 + 8 - 2
= ........
= 3 - 81 - 36 + 8 - 2
= ........
