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)

1.  divide each number by 6 and you get 4:3  answer c

2. 1x+4x=45  (the ratios give you how many of each you have)

5x=45  so x=9  that is the smallest number

3.  percent means out of 100  so 490/100  4.9

4  percent means out of 100  so .5/100  5/1000  = .005
