Solve 3x^2 5x-1=0

Evaluate

3 x^{2} \times 5 x - 1 = 0

Multiply

More Steps

15 x^{3} - 1 = 0

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

15 x^{3} = 0 + 1

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

15 x^{3} = 1

Divide both sides

\frac{15 x ^{3}}{15} = \frac{1}{15}

Divide the numbers

x^{3} = \frac{1}{15}

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

3 x^{3} = 3 \frac{1}{15}

Calculate

x = 3 \frac{1}{15}

Solution
