X^2+7x-8=0
what are the solutions

x= -8   x=1

Step-by-step explanation:

x^2+7x-8=0

Factor

What 2 numbers multiply to -8 and add to 7

8*-1 = -8

8+-1 = 7

(x+8) (x-1) =0

Using the zero product property

x+8 =0    x-1=0

x= -8   x=1

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
