Question 228369: (5x-1)(3x+7)
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! There are a couple of ways to multiply the product of two binomials like this. I recommend something called F O I L.
(5x-1)(3x+7)
F=5x*3x= 15x^2
O=5x*7=35x
I=-1*3x=-3x
L=-1*7=-7
Add together:
15x^2 + 35x - 3x - 7
15x^2 + 32x - 7
