More Steps

Multiply the terms

x^{2} \times 3 x

Multiply the terms with the same base by adding their exponents

x^{2 + 1} \times 3

Add the numbers

x^{3} \times 3

Use the commutative property to reorder the terms

3 x^{3}

3 x^{3} - 60 = 0

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

3 x^{3} = 0 + 60

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

3 x^{3} = 60

Divide both sides

\frac{3 x ^{3}}{3} = \frac{60}{3}

Divide the numbers

x^{3} = \frac{60}{3}

Divide the numbers

More Steps

Evaluate

\frac{60}{3}

Reduce the numbers

\frac{20}{1}

Calculate

20

x^{3} = 20

Take the 3 -th root on both sides of the equation

3 x^{3} = 320

Solution

x = 320
