Question

Which pair of integers would be used to rewrite the middle term when factoring|15m^2 + 17m - 4 by grouping?

A 20,-3
B -18,4
C -20,3

Answer 1

Answer: A. 20, -3
This is because if you multiplied 15 and -4 together you would get -60. And in order to get 17, you would have to take 20 minus 3 which gives us 17. 20 times -3 also gives us -60.
