Question

Multiply the binomials (3x-5)(2x+3) *

Answer 1

6x^2 - x - 15

Explanation:

Hello!

For this equation, we need to multiply the two binomials in the two sets of parentheses. This problem can be solved using FOIL.

Reminder:

FOIL stands for...

First

Outside/Outer

Inside/Inner

Last

We are going to be using this strategy! It shows us what we need to multiply, and in what order:

3x * 2x = 6x^2

3x * 3 = 9x

-5 * 2x = -10x

-5 * 3 = 15

And, all together...

6x^2 + 9x - 10x - 15

Now, we simplify it further... the 9x - 10x = -x

6x^2 - x - 15

Wala!

Hope that helped!

Answer 2

use FOIL : 6x^2+9x-10x-15 which simplifies to 6x^2-x-15
