1/x - 1/y is simplified to y/xy - x/xy and u put them together into (y-x)/xy.
and the top fraction u just y^2/y to get a common denominator.
cause if u have 1/2 + 1/4 then u simplify it to 2/4 + 1/4 which u further simplify into (2 + 1) / 4
Need Help figuring out the following:
Simplying Complex Algebraic Fractions:
The book equates this to this:
It says in the book that this step reduces the numerator and denominator to single fractions. That's fine but doesn't say how it's done. I can see the top fraction you can get by:
But i'm still unsure of that and don't know about the bottom fraction. I would normally look to multiply like
then cancel out the x and y's leaving:
Any suggestions advice would be great.

Hey guys thanks for the replies.
Hey plato. That's the answer alright. Still don't understand the books method/step in the example i posted above!
Neither do i see how you can get to xy as a common factor so easily!
Care to explain your method a little more? Would be most appreciated
