Solve (-2x+1)(-2x-7)=0

Evaluate

(- 2 x + 1) (- 2 x - 7) = 0

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

- 2 x + 1 = 0 - 2 x - 7 = 0

Solve the equation for x

More Steps

x = \frac{1}{2} - 2 x - 7 = 0

Solve the equation for x

More Steps

x = \frac{1}{2} x = - \frac{7}{2}

Solution

x_{1} = - \frac{7}{2}, x_{2} = \frac{1}{2}

Alternative Form

x_{1} = - 3.5, x_{2} = 0.5
