Solve 5y^2 7y-1=0

Evaluate

5 y^{2} \times 7 y - 1 = 0

Multiply

More Steps

35 y^{3} - 1 = 0

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

35 y^{3} = 0 + 1

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

35 y^{3} = 1

Divide both sides

\frac{35 y ^{3}}{35} = \frac{1}{35}

Divide the numbers

y^{3} = \frac{1}{35}

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

3 y^{3} = 3 \frac{1}{35}

Calculate

y = 3 \frac{1}{35}

Solution
