Hi all, I started this subject today and I have many questions of a similar nature. It would be much appreciated if someone could give me a step-by-step tutorial on how to answer a question such as this:

Factorize these quadratic expressions:

3x^2 - 7x + 2

or

9x^2 + 30x + 25

I've never used this forum before so I'm sorry if I did anything wrong.

Thanks heaps!

Sam
