Question

The binomial (y − 2) is a factor of y^2 − 10y + 16. What is the other factor?

a) (y − 5)
b) (y + 5)
c) (y − 8)
d) (y + 8)

Answer 1

HI!!

Answer 2

what would you multiply \(-2\) by to get \(+16\)?

Answer 3

which is another way of asking, what is \(16\div-2\)?

Answer 4

16/2=-8

Answer 5

right
which leaves you only one choice there

Answer 8

yes that's correct
all combinations of 16
16 x 1 = 16
4 x 4 = 16
8 x 2 = 16
but only one pair of numbers makes 10 which is 8+2
so 8 is the missing number needed to make another factor
(y-2)(y-8) good job everyone!
