Four times the square of a non-zero number is equal to sixteen times the number. What is the number?

x=4

Step-by-step explanation:

Let x be the number

4 x^2 = 16 x

subtract 16 x from each side

4x^2 -16x = 0

Factor out 4x

4x(x-4) =0

Using the zero product property

4x= 0  x-4 = 0

x=0        x=4

Since we said it was a non-zero number

x=4

x = 4

Step-by-step explanation:

Let's get the unknown number as x
