There are still no mixed numbers in this equation. To learn what "terms" are, please try this lesson.

To learn how to simplify v(v - 1), please try this lesson or this lesson.

is the solution for v(v-1) = v^2-v ?

If, by "solution", you mean "the multiplied-out form", then yes.

Re: How to solve this problem

i still dont know what to do with this

$20(v\, \frac{v\, -\, 1}{4}\) \,$

Multiply it out. Cancel the four with the twenty.

Multiply it out. Cancel the four with the twenty.

$5(v^2\, -\, 1\,) \,$

Almost. Use the correct multiplication from two posts before the above-quoted one.
