Homework Help: math

Factoring two more equations

49x^2-100z^2
32t^2-50

I'll give you a few hints.

What number squared equals 49?
What number squared equals 100?

(?x + ?z)(?x - ?z)

Fill in the question marks and you should have your factors.

Factor out 2 on the second one to start. You should be able to take it from there. (It's similar to your first problem.)

I hope this will help get you started.
