Solve 2-2x^33 - ScanMath

Question

Simplify the expression

2 - 6 x^{3}

Evaluate

2 - 2 x^{3} \times 3

Solution

2 - 6 x^{3}

Show Solution

2 (1 - 3 x^{3})

Evaluate

2 - 2 x^{3} \times 3

Multiply the terms

2 - 6 x^{3}

Solution

2 (1 - 3 x^{3})

Show Solution

x = \frac{3 9}{3}

Alternative Form

x \approx 0.693361

Evaluate

2 - 2 x^{3} \times 3

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

2 - 2 x^{3} \times 3 = 0

Multiply the terms

2 - 6 x^{3} = 0

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

- 6 x^{3} = 0 - 2

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

- 6 x^{3} = - 2

Change the signs on both sides of the equation

6 x^{3} = 2

Divide both sides

\frac{6 x ^{3}}{6} = \frac{2}{6}

Divide the numbers

x^{3} = \frac{2}{6}

Cancel out the common factor 2

x^{3} = \frac{1}{3}

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

3 x^{3} = 3 \frac{1}{3}

Calculate

x = 3 \frac{1}{3}
