Homework Help: Year 11 maths

Posted by Ulyessus on Tuesday, February 16, 2010 at 11:35pm.

My teacher said

If x-2(square root xy)=9-4(square root 2)
so since there are two square roots
-2(square root xy) equals -4(square root 2)

How is this possible, could the values be different and they are not equal.
