The following calculator can be used to solve polynomial equations. These are equations of 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 $(2x^23x5=0)$,
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 $\frac{3x^21}{2}+\frac{2x+1}{3} = \frac{x^22}{4} + \frac{1}{3}$ type (3x^2  1)/2 + (2x + 1)/3 = (x^2  2)/4 + 1/3.

Please tell me how can I make this better.
