Multiply: (4x – 7)(2x – 9)

Marizza181 [45]

Hello there!

Let's use foil.

First: 4x * 2x = 8x^2

Outside: 4x * -9 = -36x

Inside: -7 * 2x = -14x

Last: -7 * -9 = 63

Now, let's combine these.

8x^2 - 36x - 14x + 63

Finally, we can simplify this

8x - 50x + 63

I hope I helped!

Let me know if you need anything else!
