Solve -2x^2-x 1=0

Evaluate

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

Any expression multiplied by 1 remains the same

- 2 x^{2} - x = 0

Factor the expression

More Steps

- x (2 x + 1) = 0

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

- x = 0 2 x + 1 = 0

Solve the equation for x

x = 0 2 x + 1 = 0

Solve the equation for x

More Steps

x = 0 x = - \frac{1}{2}

Solution

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

Alternative Form

x_{1} = - 0.5, x_{2} = 0
