Question

I don’t understand how to do FOIL with this
2x – 3)(2x + 7)

Answer 1

`4x^2`+8x-21

Explanation:

First foil 2x to 2x to get
`4x^(2)`.
Then, foil 2x to 7 to get 14x.
Then, foil -3 to 2x to get -6x.
Then, foil -3 to 7 to get -21.
After doing all of that, you will get
`4x^2`+14x-6x-21.
Simplify it, so your final answer is
`4x^2`+8x-21
