twenty times the square of a non zero number is equal to 15 times the number
Let x be the unknown number.
Then we have:
20*x^2 = 15x
Rewrite this as:
20x^2 - 15x = 0
Factor out 5x:
5x(4x - 3) = 0
The two solutions are x = 0 and 4x - 3 = 0
We are told that the answer is non-zero so we need only to solve 4x-3 = 0 for x.
