Solve -13x=-20x^2 72

Evaluate

- 13 x = - 20 x^{2} \times 72

Multiply the terms

- 13 x = - 1440 x^{2}

Swap the sides

- 1440 x^{2} = - 13 x

Move the expression to the left side

- 1440 x^{2} + 13 x = 0

Factor the expression

More Steps

- x (1440 x - 13) = 0

When the product of factors equals 0,at least one factor is 0

1440 x - 13 = 0 - x = 0

Solve the equation for x

More Steps

x = \frac{13}{1440} - x = 0

Solve the equation for x

x = \frac{13}{1440} x = 0

Solution

x_{1} = 0, x_{2} = \frac{13}{1440}

Alternative Form

x_{1} = 0, x_{2} = 0.00902 \dot{7}
