Solve 506 - x x^3

Evaluate

506 - x \times x^{3}

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

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

Multiply the terms

More Steps

506 - x^{4} = 0

Move the constant to the right-hand side and change its sign

- x^{4} = 0 - 506

Removing 0 doesn't change the value,so remove it from the expression

- x^{4} = - 506

Change the signs on both sides of the equation

x^{4} = 506

Take the root of both sides of the equation and remember to use both positive and negative roots

x = \pm 4506

Separate the equation into 2 possible cases

x = 4506 x = - 4506

Solution

x_{1} = - 4506, x_{2} = 4506

Alternative Form

x_{1} \approx - 4.742831, x_{2} \approx 4.742831
