Spellmage ~Factoring polynominal?
« on: April 08, 2013, 08:30 pm »
I need help with this algebraic problem, I forgot how to do it. If you could show me the steps, I should be able to do the rest. If not, cool.

Problem:

2a^2 - 2b^2

I thought they had to be like terms.

I'm probably thinking of something else XD

I'm not exactly sure what you are asking me to do?

The book says to factor the polynominals, and gives these problems.

I have to find the greatest common factor of the terms, and factor the two squares. That's what the book says at least.

Can you do me a solid and do it for me?

This is one example:

3x^2 - 6x - 24

Greatest common factor: 3x^2 - 6x - 24 = 3(x^2 - 2x - 8)

Wouldn't it just be:

2(a^2-b^2)

??

Nope, it has much more work. It says factor it completely, and I don't know how to proceed.

I think I can help you, do you know the 'ac' test?

No, I don't think so @sto.

I found out the answer for the problem.

2(a+b) (a - b)

You just have to find the greatest common factor, so the GCF between 2a^2 and 2b^2 is 2. (If it was 2x and 2x^2, the GCF is 2x.)
