Question

What is this?(−2h+9)(9h−2)=

Answer 1

The answer you're looking for is "-18h^2 + 85h - 18".

This can be found by distributing "9h" into "(-2h + 9). This should give you "-18h^2 + 81h". Then youd distribute "-2" into the same parenthesis, which will give you "4h - 18".

Together, you would have "-18h^2 + 81h + 4h - 18". Combine like terms (81h and 4h), and you'll get the answer of "-18h^2 + 85h - 18".

I hope this helps!!
