Question

Factor y² + 10z - 10y-yz.
A. (z-y)(y-10)
B. (y-z)(y-10)
C. (y-z)(10 - y)

Answer 1

The answer is B,

(y-z)(y-10)

Explanation:

y^(2) + 10z - 10y-yz

Add and subtract the second term to the expression and factor by grouping.

=(y-z)(y-10)

Answer 2

Option B,
`(y - z)(y-10)`

Explanation:

Step 1: Factor out y and -z

`y^2 - 10y - yz + 10z`

`y(y - 10) - z(y - 10)`

`(y - z)(y-10)`

Answer: Option B,
`(y - z)(y-10)`
