I am interpreting the problem to be to solve the equation
(((2x^3 = 16x^2}}}
First set the equation equal to zero, by adding +-16x%5E2 to each side.
2x%5E3+-+16x%5E2+=+16x%5E2+-16x%5E2
2x%5E3+-+16x%5E2+=+0

Factor out the common factor which is 2x%5E2
2x%5E2%28x-8%29+=+0

Set each factor equal to zero:
2x%5E2+=+0 or x-8=0

The first equation 2x%5E2=0 has only one solution, x=0.
The second equation x-8=0 has one solution, x = 8.

Therefore, the final answer is x= 0 or x= 8.
