x, - 4 x^{2} - 4 x - 1 = 0

x = - \frac{1}{2}

Decimal Notation

x = - 0.5

Solution steps

- 4 x^{2} - 4 x - 1 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 4 ) \pm ( - 4 ) ^{2} - 4 ( - 4 ) ( - 1 )}{2 ( - 4 )}

(- 4)^{2} - 4 (- 4) (- 1) = 0

x_{1, 2} = \frac{- ( - 4 ) \pm 0}{2 ( - 4 )}

x = \frac{- ( - 4 )}{2 ( - 4 )}

\frac{- ( - 4 )}{2 ( - 4 )} = - \frac{1}{2}

x = - \frac{1}{2}

The solution to the quadratic equation is:

x = - \frac{1}{2}

x, x^{2} + m x + 1 = m x^{2} + 2 x

w^{2} + w - 20 = 0

s^{2} + s - 4 = 0

x, 4 x^{2} - 1 = 0

8 x^{2} + 53 x - 21 = 0
