Factoring

Hi guys,

Having trouble with factoring polynomials.

1. a^2 - b^2 + 4b - 4

2.  4t^3 - s^2t - 6stz - 9tz^2

Thanks.

Re: Factoring

Hi panday;

I know you solved it but this is what I did. I used trial and error on (a-b)(a+b) adding a third term for each and came up with (a + b - 2)(a - b + 2).

Just got this one right now.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Factoring

Wow, this is a really cool site! I have an assignment from my instructor to present a great math website and I am going to use this one. I am taking Math Across the Generations, I am a junior in college. I am just going to try and learn more about the website first . Any suggestions?
