#72 from the Chapter Review

Can anyone help me figure out #72 from the Chapter Review Problems?

72. (2k-1) - (3k^2-2k+6)

  1. Dani, all you have to do is change the signs for each term in the second polynomial. for this problem it would look like this:
    (2k-1) - (3k^2-2k+6)
    =2k-1-3k^2+2k-6
    (next you combine like terms)
    so you get -3k^2-7 as your final answer.
