Solve 4x^2 12x-15=5

Evaluate

4 x^{2} \times 12 x - 15 = 5

Multiply

More Steps

48 x^{3} - 15 = 5

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

48 x^{3} = 5 + 15

Add the numbers

48 x^{3} = 20

Divide both sides

\frac{48 x ^{3}}{48} = \frac{20}{48}

Divide the numbers

x^{3} = \frac{20}{48}

Cancel out the common factor 4

x^{3} = \frac{5}{12}

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

3 x^{3} = 3 \frac{5}{12}

Calculate

x = 3 \frac{5}{12}
