Polynomial equation solver

This calculator solves equations that are reducible to polynomial form , such as $ \color{blue}{2(x+1) + 3(x-1) = 5} $ , $ \color{blue}{(2x+1)^2 - (x-1)^2 = x} $ and $ \color{blue}{ \frac{2x+1}{2} + \frac{3-4x}{3} = 1} $ . The calculator will try to find an exact solution; if this is not possible, it will use the cubic or quartic formulas. The calculator will walk you through each step and give you a detailed explanation on how to simplify and solve the equation.

Computation Failed

Hint:

Try to use fractions instead of decimals.

Polynomial equation solver

Solve equations without a variable in the denominator.
