Question 64830: I can not figure out this question.
5. Simplify by (multiplying out) or by (factoring and then dividing):
a. (14x to the 3rd y to the 4th z)/(7x to the 4th y to the 2nd z to the 4th)
b. 2xy(3x to the 2nd y - 5x to the 2nd y + 6)
c. (2x + y - 3)(3x - 2y)
d. (2x to the 3rd + 7x to the 2nd - x - 2)/(2x + 1)

I had to use long division for this one, which is all but impossible to show you on this.
The answer is highlight%28x%5E2%2B3x-2%29.
If you have Word, I have mathtype and can send you an attachment to show you how to get this.
