Multiply the terms

4 x^{2} \times 52 x

Multiply the terms

208 x^{2} \times x

Multiply the terms with the same base by adding their exponents

208 x^{2 + 1}

Add the numbers

208 x^{3}

208 x^{3} - 3 = 0

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

208 x^{3} = 0 + 3

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

208 x^{3} = 3

Divide both sides

\frac{208 x ^{3}}{208} = \frac{3}{208}

Divide the numbers

x^{3} = \frac{3}{208}

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

3 x^{3} = 3 \frac{3}{208}

Calculate

x = 3 \frac{3}{208}
