Solve 8y^2 31y-4=0

Evaluate

8 y^{2} \times 31 y - 4 = 0

Multiply

More Steps

248 y^{3} - 4 = 0

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

248 y^{3} = 0 + 4

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

248 y^{3} = 4

Divide both sides

\frac{248 y ^{3}}{248} = \frac{4}{248}

Divide the numbers

y^{3} = \frac{4}{248}

Cancel out the common factor 4

y^{3} = \frac{1}{62}

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

3 y^{3} = 3 \frac{1}{62}

Calculate

y = 3 \frac{1}{62}
