Thank you for the opportunity to help you with your question! Hope your day is going well!

This is partly a laws of exponents problem. We need to distribute the x to both terms inside the parenthesis.

Let's split this into two part.

x * x^2 (since they have the same base,and they are multiplied: you add the exponents)

x^(1+2)

x^3

x * -9y^2 (notice that there are not any common basis, thus we multiply the whole thing by x as follows)

-9xy^2.

Combine these two things together.

x^3-9xy^2.

Thus our answer is x^3-9xy^2.

Please let me know if you need any clarification. I'm always happy to answer your questions.
