What is the simplest form of the expression below? f 2 - 25 5 * f f - 5

(f^2 - 25) / 5 * f / (f-5)

Factor the difference of squares:

(f-5) (f+5) / 5 * f / (f-5)

Cancel "f-5" from numberator and denominator:

(f+5) / 5 * f/1

Multiply fractions:

f (f+5) / 5

Since this doesn't match any of the answers,

we should distribute the "f" in the numerator:

(f^2+5f) / 5

Thus, the best answer of the selection is:

(B) (f^2-5f) / 5

The answer is 25f to the second power
