x^4-30x^2+25=0
You asked:
Solve the equation \({x}^{4} - 30 \cdot {x}^{2} + 25 = 0\) for the variable \(x\).
MathBot Answer:
The 4 solutions to the equation are: \[\begin{aligned}x &= \sqrt{15 - 10 \sqrt{2}} \approx 0.92620968\\x &= \sqrt{15 + 10 \sqrt{2}} \approx 5.3983456\\x &= - \sqrt{15 - 10 \sqrt{2}} \approx -0.92620968\\x &= - \sqrt{15 + 10 \sqrt{2}} \approx -5.3983456\end{aligned}\]
