$(1/2\sqrt{Y}) (-6\sqrt{Y)}$

actually it's a -1/2

|dw:1351114021944:dw|

If the 1/2 is also negative then it would be$3y$

I don't get it

What do you "don't get"?

the multiplication

$\sqrt{a}\times \sqrt{a}= a$

Or $(a ^{1/2 }) x (a ^{1/2})=a ^{(1/2 + 1/2)}= a ^{1}=a$

(-2)(-3)=+6 Multiplication when signs are alike. Although you were confusing about the signs.

(-1/2)(-6)= 3 see above.

:/ I'm using the foil method and I'm not getting it. Thanks.

I just multiplied the two terms as they were each enclosed by parentheses (no need to foil)

Restate the problem.

so all you did was mutiply 1/2 by -6 and mulitplied radical y by radical y. so then you get -3y?

Yes, I believe that was the problem.

I have a test on this tomorrow. I'm stressed :/
