You asked:

Solve the equation 5x+5x3=105 x + 5 {x}^{3} = 10 for the variable xx.

MathBot Answer:

The 3 solutions to the equation are: x=1x=−12−7i2≈−0.5−1.3228757ix=−12+7i2≈−0.5+1.3228757i\begin{aligned}x &= 1\\x &= - \frac{1}{2} - \frac{\sqrt{7} i}{2} \approx -0.5 -1.3228757 i\\x &= - \frac{1}{2} + \frac{\sqrt{7} i}{2} \approx -0.5 + 1.3228757 i\end{aligned}

ii is the imaginary unit, defined as i2=−1i^2 = -1.
