Solve $$$\left(x + 9\right)^{2} + 36 = 102$$$ for $$$x$$$ (real roots)

The calculator will try to solve the equation $$$\left(x + 9\right)^{2} + 36 = 102$$$ for $$$x$$$ (find the real roots) on the interval $$$\left(-\infty, \infty\right)$$$.
Leave empty for autodetection.
Optional.
If the interval is specified, the checkbox will be checked automatically.

Your Input

Solve the equation $$$\left(x + 9\right)^{2} + 36 = 102$$$ for $$$x$$$ on the interval $$$\left(-\infty, \infty\right)$$$.

Answer

Real roots

$$$x = -9 + \sqrt{66}\approx -0.87596159536404$$$A

$$$x = -9 - \sqrt{66}\approx -17.12403840463596$$$A
