Hi all,

I cannot understand why this does not work.

So I thought I could just cancel out the fraction x^2 in both the numerator and dominator as it is a common factor.

Why does this not work?

For example, the fraction below we can simplify it by dividing top and bottom by 5 and p^2 as they are common factors.

So why does the above one not let us divide by x^2 as it is also a common factor?
