The binomial (y-2) is a factor of y2-10y+16. what is the other factor?

Y^2 - 10y + 16

the last sign in ur problem...the one before the 16..it is a +this means that both ur factors will have the same signthe first sign...the one before the 10y is a -this means that both ur factors will have a negative sign

now, we have to find 2 numbers, then when added = -10 and when multiplied = 16-8 + (-2) = -10-8 * -2 = 16so ur numbers are -8 and -2

y^2 - 10y + 16
(y - 2)(y - 8) <===
