Use zero product property to solve.
F(x)=3x(2x-6)

x=0    x=3

Step-by-step explanation:

F(x)=3x(2x-6)

Set equal to zero

0 =3x(2x-6)

Using the zero product property

3x =0   2x-6 =0

x =0     2x = 6

             x = 6/2

             x = 3

x = 0 or x = 3

Step-by-step explanation:

Set the output to 0

0 = 3x(2x-6)

Set factors equal to 0.

3x = 0

x = 0

2x - 6 = 0

2x = 6

x = 3
