Solve 5x^2 6x = 21

Evaluate

5 x^{2} \times 6 x = 21

Multiply

More Steps

30 x^{3} = 21

Divide both sides

\frac{30 x ^{3}}{30} = \frac{21}{30}

Divide the numbers

x^{3} = \frac{21}{30}

Cancel out the common factor 3

x^{3} = \frac{7}{10}

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

3 x^{3} = 3 \frac{7}{10}

Calculate

x = 3 \frac{7}{10}

Solution
