How do I factor 4x^212x+8?
so far I took out the Greatest Common Factor.
4(x^23x+2)
What next?

do you know how to use the diamond? or were you taught with the FOIL square?

Never heard of diamond. I've heard of FOIL.

Then you would use FOIL, and find which two numbers multiply to get 2, and add to get 3

Ok that's what I thought. I tried to do that.
2 x 1=2
2 + 1=1
2 x 1=3
2+1=3
1 x 2=2
1+2=1
I don't know what other numbers multiply to 2. 
Try making both 2 and 1 negative

oh wow haha.
I see.
