Solve $$$\lambda^{2} - 1 = 0$$$ for $$$\lambda$$$

The calculator will try to solve the equation $$$\lambda^{2} - 1 = 0$$$ for $$$\lambda$$$ (find the real and complex roots).

Solve the equation $$$\lambda^{2} - 1 = 0$$$ for $$$\lambda$$$.

$$$\lambda = -1$$$A

$$$\lambda = 1$$$A

It seems that there are no complex roots.
