    use this formula (a+b)^2 = a^2 + 2ab + b^2 here a=x and b=h

    but when i get to 2xh+h^2 divied by h can i cancel the h in the 2xh with the other h's or can i not do that because it is a term with x? if that makes sense

    You can factor out h on top And assuming h does not equal 0 You can do what after that?
