Here are some questions that I can't solve...

factorization:

1.a^2x+2+2a^2+x

2.-(3+a)(5-b)+3c(b-5)

3.-a-b+3ab+3a^2

4.x^2-y^2+x-y

5.x^2-y^2+3x+3y

6.2c^2-8d^2+c-2d

That's all, hope you can help me :)

Thanks

Hope this was of some help.

That was exactly what I was looking for :)

- Mar 17th 2006, 09:32 AMdgolverkHmm..
While doing my homework I found 3 more problems...

1.3x(a-b)+4y(b-a) I don't understand how can I make two (b-a) or (a-b)

2.24X^2(d-c)+3x^2(-d+c)

3.3(a+b-c)-d(a+b-c)

Those are the 3 last questions in my homework...

Thanks again for helping! - Mar 17th 2006, 12:28 PMearbothQuote:

Nice Weekend to you.

I made a mistake in the last question it supposed to be like that:

3(a+b+c)-d(a+b-c)

What is the answer for that one?

and those:

x^3-xy^2+y^2+xy

x^4-y^4+y-x - Mar 18th 2006, 10:44 AMdgolverk
guys it's really urgent, that's for tomorrow...

Thanks
