Solve x = -2x^2 10

Evaluate

x = - 2 x^{2} \times 10

Multiply the terms

x = - 20 x^{2}

Swap the sides

- 20 x^{2} = x

Move the expression to the left side

- 20 x^{2} - x = 0

Factor the expression

More Steps

- x (20 x + 1) = 0

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

- x = 0 20 x + 1 = 0

Solve the equation for x

x = 0 20 x + 1 = 0

Solve the equation for x

More Steps

x = 0 x = - \frac{1}{20}

Solution

x_{1} = - \frac{1}{20}, x_{2} = 0

Alternative Form

x_{1} = - 0.05, x_{2} = 0
