Solve x^3-3x^23-x=0

Evaluate

x^{3} - 3 x^{2} \times 3 - x = 0

Multiply the terms

x^{3} - 9 x^{2} - x = 0

Factor the expression

x (x^{2} - 9 x - 1) = 0

Separate the equation into 2 possible cases

x = 0 x^{2} - 9 x - 1 = 0

Solve the equation

More Steps

x = 0 x = \frac{9 + 85}{2} x = \frac{9 - 85}{2}

Solution

x_{1} = \frac{9 - 85}{2}, x_{2} = 0, x_{3} = \frac{9 + 85}{2}

Alternative Form

x_{1} \approx - 0.109772, x_{2} = 0, x_{3} \approx 9.109772
