What types of equations can this tool solve?

This solver currently handles Linear equations of the form ax + b = 0, Quadratic equations of the form ax² + bx + c = 0, and 2-variable Simultaneous equations.

How are complex quadratic roots handled?

If the discriminant (D = b² - 4ac) is negative, the calculator automatically computes complex conjugate roots (of the form x = real ± imag*i) and displays the imaginary steps.
