Solve -3 x^4 -6 x^3 -6 x^2 -8 x

Evaluate

- 3 x^{4} - 6 x^{3} - 6 x^{2} - 8 x

To find the roots of the expression,set the expression equal to 0

- 3 x^{4} - 6 x^{3} - 6 x^{2} - 8 x = 0

Factor the expression

- x (3 x^{3} + 6 x^{2} + 6 x + 8) = 0

Divide both sides

x (3 x^{3} + 6 x^{2} + 6 x + 8) = 0

Separate the equation into 2 possible cases

x = 0 3 x^{3} + 6 x^{2} + 6 x + 8 = 0

Solve the equation

x = 0 x \approx - 1.733624

Solution

x_{1} \approx - 1.733624, x_{2} = 0
