solve x^4-4x^2-x+2=0
You asked:
Solve the equation \({x}^{4} - 4 \cdot {x}^{2} - x + 2 = 0\) for the variable \(x\).
MathBot Answer:
The 4 solutions to the equation are: \[\begin{aligned}x &= -1\\x &= 2\\x &= - \frac{1}{2} + \frac{\sqrt{5}}{2} \approx 0.61803399\\x &= - \frac{1}{2} - \frac{\sqrt{5}}{2} \approx -1.618034\end{aligned}\]
