Question

Can someone help me with factoring?

Answer 1

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

Answer 2

No my friend. I have specifiy problems. For example.

I dont know to expand the following expression

Answer 3

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?

Answer 4

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.

Answer 5

yup
you got it

Answer 6

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?

Answer 7

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

Answer 8

can you tell me which part does not make sense?

Answer 9

i know how it feels, english isn't my first language
