$x^{2}$ +18x+30=2 $\sqrt{xx + 18x+45\}$
You asked:
Solve the equation \({x}^{2} + 18 x + 30 = 2 \cdot \sqrt{x x + 18 x + 45}\) for the variable \(x\).
MathBot Answer:
The 2 solutions to the equation are: \[\begin{aligned}x &= -9 + \sqrt{61} \approx -1.1897503\\x &= -9 - \sqrt{61} \approx -16.81025\end{aligned}\]
