Solve 2x^3-54 - ScanMath

Evaluate

2 x^{3} - 54

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

2 x^{3} - 54 = 0

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

2 x^{3} = 0 + 54

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

2 x^{3} = 54

Divide both sides

\frac{2 x ^{3}}{2} = \frac{54}{2}

Divide the numbers

x^{3} = \frac{54}{2}

Divide the numbers

3 x^{3} = 327

Calculate

x = 327
