Question

y square minus y z minus 5 y + 5z​

Answer 1

Answer:

Whenever you factorize a polynomial, try figuring out common variables in pairs of terms.

y²-yz-5y+5z

Taking y in the first two terms and z in the second two terms as common

=y (y-z)-5 (y-z)

Now taking (y-z) as common we get,

=(y-5)(y-z)

Ans) (y-z)(y-5)

Answer 2
