Multiply the terms

35 x^{2} \times 23 x

Multiply the terms

805 x^{2} \times x

Multiply the terms with the same base by adding their exponents

805 x^{2 + 1}

Add the numbers

805 x^{3}

805 x^{3} - 6 = 0

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

805 x^{3} = 0 + 6

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

805 x^{3} = 6

Divide both sides

\frac{805 x ^{3}}{805} = \frac{6}{805}

Divide the numbers

x^{3} = \frac{6}{805}

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

3 x^{3} = 3 \frac{6}{805}

Calculate

x = 3 \frac{6}{805}

Solution
