Question

multiply (4x-3)(2x+5)

Answer 1

In this case a common process used is FOIL which means First Outer Inner Last. It stands for the order in which you mutiply the terms. The first of both is what you mutiply first.

Answer 2

4x(2x) are the first terms: \[8x ^{2}\]
4x(5) are the outer terms: 20x
-3(2x) are the inner terms: -6x
-3(5) are the last terms: -15

Therefore: \[8x ^{2}+12x-15\] Should be your final answer after you combime the like terms.
