Question 42960
Actually, you have an extra f on both terms, as I get on the result {{{f+5}}}

When dividing and multiplying polynomials, a good rule of thumb is that you add the exponents for the multiply, and when dividing, you subtract (when the terms have the same variable, of course!). So, you could verify your result by multiplying {{{f^2 * f = f^3}}}, which is not our answer. When using the subtract rule, you easily get {{{(f^2)/f^1 = f^(2-1) = f^1 = f}}}. Other than that, the rest is fine.
