Question

a(squared)/(a-b)+ b(squared)/(b-a)

Answer 1

That equals (a^2 - b^2)/(a-b) = a + b, if simplification is what you are after.

Answer 2

can you please show me how you get this that's what the book says but that is not what i get...sorry for the trouble.. i want to understand it too not just have an answer

Answer 3

i get the a^2-b^2 / a-b... how does that turn into (a+b)

Answer 4

a^2 - b^2 = (a-b)(a+b)

The a-b in the denominator cancels out the one in the numerator
