Answer:
(y - 7)(y - 4)
Step-by-step explanation:
The given expression is y^2 - 11y + 28
Now find the factor of 28 such that when you add the factors, we have to get -11
The right factors of 28.
-7 * - 4 = 28
-7 + (-4) = -11
The right factors are -7 and -1
y^2 - 11y + 28 = y^2 -7y - 4y + 28
= y(y - 7) -4(y - 7)
= (y - 7)(y - 4)
Therefore, y^2 -11y + 28 = (y - 7)(y - 4)
Thank you.
