Question

Factors of y(y – z) + 9(z - y)​

Answer 1

Answer:

y square - yz +9z - 9y

this is the answer

Answer 2

Answer:

Step-by-step explanation:

Given that,

y ( y - z ) + 9 ( z - y )

= y² - yz + 9z - 9y

= y² - 9y - yz + 9z

= y ( y - 9 ) - z ( y - 9 )

= ( y - z ) ( y - 9 ) is the answer.
