Question 243315: what are the GCF of, and how do you show the work?
15y-60.
9Z%5E4%2B27z.
-3z%5E5w%5E2-18z%5E3w%5E4.
(x-5%29%28x%2B7%29=%28x-5%29%28x%2B9%29.

You can put this solution on YOUR website!
15y-60. divide by 15.
15(y-4) ans
9Z%5E4%2B27z. divide by 9z.
9z(z^3+3) ans.
-3z%5E5w%5E2-18z%5E3w%5E4. divide by -3z^3w^2.
-3z^3w^2(z^2-6w^2) ans.
(x-5%29%28x%2B7%29=%28x-5%29%28x%2B9%29. This is an invalid equation.
Cancelling out the (x-5) terms you have:
x+7=x+9
x-x=9-7
0=2 does not compute.
