Quadratic Equations Solver play online

The user can resolve any second degree equation. To do this you have to introduce the value of the coefficients a, b and c. If the equation is in standard form,
coefficient a is the number that multiplies to x squared, coefficient b is the number that multiplies to x and coefficient c is the independent term.
If the coefficients a, b and c are not equal to zero the second degree equation is complete. In this case we solve the equation with the formula.
However, if b=0 or c=0 the equation is incomplete and we will use alternative ways to solve it.
If b=0, we solve the incomplete second degree equation as if it is a first degree equation and we calculate the square root at the end.
If c=0, we solve the incomplete second degree equation with the factorization and make each factor equal to zero.
The application explains each operation step by step.
