Question

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

Answer 1

Answer:

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

Step-by-step 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, $(y - z)(y-10)$

Answer 2

Answer:

The answer is B,

(y-z)(y-10)

Step-by-step explanation:

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

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

=(y-z)(y-10)
