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%5E2-1=3
-1.5x%5E2%2B5.2x-1-3=0
-1.5x%5E2%2B5.2x-4=0
15x%5E2-52x%2B40=0, through multiplying left and right by -10.

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