Radical equations

The app solves an equation with the unknown under a root by isolating the root and squaring. Squaring can add roots that do not satisfy the equation – so a check always follows and the roots that fail it are discarded.

Examples

Squaring and a check – one of the roots does not satisfy the equation.
Input: sqrt(x+5) = x - 1
sqrt(x+5) = x - 1
sqrt(x+5) = x - 1sqrt(x+5) = x - 1
