5 x^{2} - 16 x - 16 = 0

x = 4, x = - \frac{4}{5}

Decimal Notation

x = 4, x = - 0.8

Solution steps

5 x^{2} - 16 x - 16 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 16 ) \pm ( - 16 ) ^{2} - 4 \cdot 5 ( - 16 )}{2 \cdot 5}

(- 16)^{2} - 4 \cdot 5 (- 16) = 24

x_{1, 2} = \frac{- ( - 16 ) \pm 24}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 16 ) + 24}{2 \cdot 5}, x_{2} = \frac{- ( - 16 ) - 24}{2 \cdot 5}

x = \frac{- ( - 16 ) + 24}{2 \cdot 5} : 4

x = \frac{- ( - 16 ) - 24}{2 \cdot 5} : - \frac{4}{5}

The solutions to the quadratic equation are:

x = 4, x = - \frac{4}{5}

x, y^{2} + x^{2} = z^{2}

(y + 7) (y - 3) = 0

x c (x + 2) - 5 = b (x - 3)

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

u^{2} - 18 u
