Solve (¼)*x^3(x+4) +8=22

Evaluate

\frac{1}{4} x^{3} (x + 4) + 8 = 22

Move the expression to the left side

\frac{1}{4} x^{3} (x + 4) + 8 - 22 = 0

Subtract the numbers

\frac{1}{4} x^{3} (x + 4) - 14 = 0

Calculate

More Steps

\frac{1}{4} x^{4} + x^{3} - 14 = 0

Factor the expression

\frac{1}{4} (x^{4} + 4 x^{3} - 56) = 0

Divide both sides

x^{4} + 4 x^{3} - 56 = 0

Calculate

x \approx 2.094513 x \approx - 0.756208 - 2.294155 i x \approx - 0.756208 + 2.294155 i x \approx - 4.582097

Solution

x_{1} \approx - 4.582097, x_{2} \approx - 0.756208 + 2.294155 i, x_{3} \approx - 0.756208 - 2.294155 i, x_{4} \approx 2.094513
