Solve 2x^3 (5x -7) =47

Evaluate

2 x^{3} (5 x - 7) = 47

Expand the expression

More Steps

10 x^{4} - 14 x^{3} = 47

Move the expression to the left side

10 x^{4} - 14 x^{3} - 47 = 0

Calculate

x \approx 1.993376 x \approx 0.311174 - 1.357423 i x \approx 0.311174 + 1.357423 i x \approx - 1.215725

Solution

x_{1} \approx - 1.215725, x_{2} \approx 0.311174 + 1.357423 i, x_{3} \approx 0.311174 - 1.357423 i, x_{4} \approx 1.993376
