Polynomial equation solver

This calculator solves polynomial equations in the form $P(x)=Q(x)$, where $P(x)$ and $Q(x)$ are polynomials. Special cases of such equations are:

1. Linear equation $(2x+1=3)$
2. Quadratic Equation $(2x^2-3x-5=0)$,
3. Cubic equation $(5x^3 + 2x^2 - 3x + 1 = 0)$ . . .

How to use this calculator?

Example 1: to solve (2x + 3)² - 4(x + 1)² = 1 type (2x + 3)^2 - 4(x + 1)^2 = 1.

Example 2: to solve $\frac{3x^2-1}{2}+\frac{2x+1}{3} = \frac{x^2-2}{4} + \frac{1}{3}$ type (3x^2 - 1)/2 + (2x + 1)/3 = (x^2 - 2)/4 + 1/3.
