Answer 2

Answer:

9w² - 18w

or

9w(w - 9)

Step-by-step explanation:

Let's start by applying the distributive property to all of the expressions:

5w(2w - 7) + w(3w + 8) - 4w² + 9w

10w² - 35w + 3w² + 8w - 4w² + 9w

Now, combine the like terms:

9w² - 18w

You could stop there, but if you wanted to, you could factor out a 9 and a w:

9w(w - 9)

Hope that helps :) If you have any questions, please comment on this thread! I'm more than willing to help!
