Factor the expression: 7x(x^2-1)-3(x^2-1)

x = 1

Step-by-step explanation:

The factors of the given expression is as follows:

If we considered x = 1

So

7 - 3 -7 + 3 = 0

0 = 0

Hence, the factor would be 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
