Year 11 maths

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.

    your teacher is dead wrong.


    sqrt25 is not equal to sqrt196, ever.
    Point this out to your teacher.
