## anonymous 5 years ago Can someone help me with factoring?

1. anonymous

factoring is one of the hardest (but easier as you practice) concepts you have to learn it's important BUT it's very very hard to explain over the internet. http://tutorial.math.lamar.edu/Classes/Alg/Factoring.aspx this site does a very good job of explaining it take a look at example 3 part e if you understand the basics and want an "advanced" one good luck

No my friend. I have specifiy problems. For example. I dont know to expand the following expression

3. anonymous

you said factoring in the post btw but this isn't as bad as it looks $(\frac{1}{2} - 2x^2 + y^2)^2 = (\frac{1}{2} - 2x^2 + y^2)(\frac{1}{2} - 2x^2 + y^2)$ the next part is just multiplying it out do you know how to do it?

4. anonymous

I remember now. If Im not wrong, we have an expression like this (a+b+c)^2=a^2+b^2+c^2+2(ab+ac+bc) Please correct me if im wrong.

5. anonymous

yup you got it

though that is with a more specific format the question must be asking for a square if the question was (a + b + c)(d + e + f) it would be (ad + ae + af + bd + be + bf + cd + ce + cf) does that make sense?

7. anonymous

Not exactly. Sorry my english is not so good. Specify a little bit

8. anonymous

can you tell me which part does not make sense?

9. anonymous

10. anonymous

lol so you understand? keep the link that i sent it look at it if you have time, then again, it's for factoring... if you need help with factoring, that is definitely the site to go to like i said before, factoring is a difficult to explain, especially more complicated ones
