Answer: 9x²-81x
Step-by-step explanation:
1. Reorder the terms like this: (9x)• (x-9)
2. Remove unnecessary Parentheses like this: 9x•(x-9)
3. Distribute 9x through the Parentheses like this:
9x would become 9x² (because I combined 9x and 9x which become 9x²)
(x-9) would become -81x (so if you need further explanation I took the (x-9) and made it -9x then multiplied it by the 9x because of distributive property.)
The solution: 9x²-81x
