Question 587928: 50g^2-8
What do you do if its not a perfect square?

I imagine you want to factor 50g%5E2-8 and are concerned that 50g%5E2 and 8 are not perfect squares. Unless there is some evil teacher that wants to make you use some awkward square roots, there must be a way.
Fortunately 50 and 8 divide by 2 evenly, so your first factoring task would be to take out that common factor 2.
HINT: Always look for common factors first.
After that, you end up with perfect squares 25g%5E2 and 4, and wonder why you did not see it coming from the start.
50g%5E2-8=2%2825g%5E2-4%29=2%285g%2B2%29%285g-2%29
