Solve -2(4x^3)-(x-7)=46

Evaluate

- 2 \times 4 x^{3} - (x - 7) = 46

Simplify

More Steps

- 8 x^{3} - x + 7 = 46

Move the expression to the left side

- 8 x^{3} - x + 7 - 46 = 0

Subtract the numbers

- 8 x^{3} - x - 39 = 0

Factor the expression

- (8 x^{3} + x + 39) = 0

Divide both sides

8 x^{3} + x + 39 = 0

Calculate

x \approx - 1.671034 x \approx 0.835517 + 1.48972 i x \approx 0.835517 - 1.48972 i

Solution

x_{1} \approx 0.835517 - 1.48972 i, x_{2} \approx 0.835517 + 1.48972 i, x_{3} \approx - 1.671034
