Every question like this I have gotten wrong:
"Multiply or divide the expression below. Leave your answer as simplified as possible."
(3x1)(x+7) 10(2x5)
 • 
4(2x5) (4x+1)(x+7)
This is from the college preparatory math section 10.1.4
I need to find what the denominator can not equal.

Go to webmath, it's a site on the internet. When you get there click on home and scroll down to complex numbers, multiplying. There you can type in the problem and it will show you step by step how to do this. Your gonna love this site. Take care!
