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. :wink:


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

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

Multiply it out. Cancel the four with the twenty. :wink:

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