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.
Solve equation$$x^2+4x = 0$$
solution
$$ \begin{matrix}x_1 = 0 & x_2 = -4 \\[1 em] \end{matrix} $$explanation
In order to solve $ \color{blue}{ x^{2}+4x = 0 } $, first we need to factor our $ x $.
$$ x^{2}+4x = x \left( x+4 \right) $$$ x = 0 $ is a root of multiplicity $ 1 $.
The second root can be found by solving equation $ x+4 = 0$.
