The other factor is (y-8).

Step-by-step explanation:

Given : The binomial (y-2) is a factor of y^2 - 10y + 16

To find : What is the other factor?

Solution :

We have given the quadratic equation y^2 - 10y + 16

One of the factor is (y-2).

To find other factor we factorize the given quadratic equation,

$y^{2}-10y+16=0$

Applying middle term split,

$y^{2}-8y-2y+16=0$

y(y-8)-2(y-8)=0

(y-8)(y-2)=0

The other factor is (y-8).
