Question 934648
The solution should not be so bad.  That is a quadratic equation.  If check for the numerators for the decimalized mixed number coefficients, the lowest common denominator is 10.


The three first steps:
{{{5.2x-1.5x^2-1=3}}}
{{{-1.5x^2+5.2x-1-3=0}}}
{{{-1.5x^2+5.2x-4=0}}}
{{{15x^2-52x+40=0}}}, through multiplying left and right by {{{-10}}}.


Easier to not check factorability.  Just use the general solution of a quadratic equation.
