Question 110761: Can you figure this out for me!
1. Factor
-9w+9u-tw-+ut
2. Factor
6b^4/5c^4d^2/3ab^3/15c^2d
3. x sqrt.80xw^2+5wsqrt.5x^3
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! 1. Factor
-9w+9u-tw-+ut
-9(w-u)+t(w-u)
(w-u)(t-9)
---------------------
2. Factor
6b^4/5c^4d^2/3ab^3/15c^2d
Invert the denominator and multiply:
[6b^4 / 5c^4d^2] * [15c^2d / 3ab^3]
Cancel factors tht are comon a numerator and a denominator
like 3,5,c^2, b^3, d
= [ 6b / c^2d ] * [1/a]
= [6b/ac^2d]
------------------------------
3. xsqrt(80xw^2) + 5wsqrt(5x^3)
= 4xw sqrt(5x) + 5xw sqrt(5x)
= 9xw sqrt(5x)
