**Katie**, Thursday, September 10, 2009 at 6:20pmdo you know how to use the diamond? or were you taught with the FOIL square?

**Loretta**, Thursday, September 10, 2009 at 6:22pmNever heard of diamond. I've heard of FOIL.

**Katie**, Thursday, September 10, 2009 at 6:24pmThen you would use FOIL, and find which two numbers multiply to get 2, and add to get -3

**Loretta**, Thursday, September 10, 2009 at 6:27pmOk 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.

**Katie**, Thursday, September 10, 2009 at 6:29pmTry making both 2 and 1 negative
