Add and Simplify: 100x/x+10 + x^3/x+10

I have the answer as X^3+100x/X+10 is this correct?

• I need someone to check this -

Are the x+10 terms in denominators? If so, you should have put parentheses around them.

If that is the case, then yes,

It can also be written
x(x^2+100)/(x+10)

If that were a (x^2-100) in the numerator, you could simplify it even more by factoring.
