Question 205922
It's not an equation, but an expression, since it 
does not contain an equal sign " = ".
You cannot "solve" an expression.

All you can do with this expression

{{{(4x3-9x)/(2x-1)}}}

to begin with is to factor out x in the numerator:

{{{(x(4x^2-9))/(2x-1)}}}

and then you can factor what's in the parentheses as
the difference of two perfect squares:

{{{(x(2x-3)(2x+3))/(2x-1)}}}

But then nothing cancels, so you stop there.
