Solve $$$\lambda^{2} - 4 \lambda - 4 = 0$$$ for $$$\lambda$$$

The calculator will try to solve the equation $$$\lambda^{2} - 4 \lambda - 4 = 0$$$ for $$$\lambda$$$ (find the real and complex roots).

Solve the equation $$$\lambda^{2} - 4 \lambda - 4 = 0$$$ for $$$\lambda$$$.

$$$\lambda = 2 - 2 \sqrt{2}\approx -0.82842712474619$$$A

$$$\lambda = 2 + 2 \sqrt{2}\approx 4.82842712474619$$$A

It seems that there are no complex roots.
