You can substitute in the values. So m=-4 so put that in instead of m. And p=2 so put that in instead of p. The problem is then (-4)(2)-5(2). Simplify to -8-10 And your final answer is -18. Wasnt aware you could edit these after you made them haha. I did correct my math in my comments riaght after the post. Sorry about that guys ^.^
