Answer: The absolute value of 8

Step-by-step explanation:

Absolute value means how far away from 0 a number is.

If you have a number line, and the question is what is the absolute value of -10, for example, the answer would be ten, because it is 10 away from zero. if it was the absolute value of 10, however, it would still be ten, not -10.

Complete y^2+15y+56=(y+7)(y+?) ...?
Rufina [12.5K]
The two factors of a quadratic equation can be multiplied to form the original equation. Let the missing term be a:
y² + 15y + 56 = (y + 7)(y + a)
y² + 15y + 56 = y² + (7 + a)y + 7a
We can now compare the coefficient of the like terms, either the one with y or the one without y, and find the value of a.
15 = 7 + a; a = 8
OR
56 = 7a; a = 8

Second factor is (y + 8)
