How do I add x/(x+1) + x^3?
How do I divide those two numbers as well?

get a common denominator, x+1

x/(x+1) + x^3(x+1)/x+1

x(1 + x^3 + x^2)/(x+1)

divide? I am not certain what you mean.

Thank you so much!
What I mean is how do I divide
x/(x+1) by x^3?

The answer to your last question would be 1/[(x+1)x^3]
The x+1 stays in the denominator, but the x/x^3 becomes the x^2 term in the denominator.

do you now what is 49*63 is
