Solve 4x^2 12x - 16 = 0

Evaluate

4 x^{2} \times 12 x - 16 = 0

Multiply

More Steps

48 x^{3} - 16 = 0

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

48 x^{3} = 0 + 16

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

48 x^{3} = 16

Divide both sides

\frac{48 x ^{3}}{48} = \frac{16}{48}

Divide the numbers

x^{3} = \frac{16}{48}

Cancel out the common factor 16

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}
