Jaime Huff · Answer 1

In this case sense its m = - 3 then your answer is - 6

Goon · Answer 2

Since we already know the value of m, this one is easy to solve. All we have to do is substitute in a - 3 for every m in the equation.

m4-m3-2m2+10m+15

(-3) 4 - (-3) 3-2 (-3) 2+10 (-3) + 15

-6

When m = - 3, this expression equals - 6.
