factor by grouping

Question

Factor by grouping.

25y-yv+5v-5y2

Answer 1

Group it like this:

(25y - 5y²) + (-yv + 5v)

Factor out 5y from the first group and v from the second group to get:

5y(5 - y) + v(-y + 5) then re-order the send group to bbe:

5y(5 - y) + v(5 - y)

Then factor out the common term "5 - y" to get:

(5 - y)(5y + v)
