10 x^{2} - 11 x - 8 = 0

x = \frac{8}{5}, x = - \frac{1}{2}

Solution steps

10 x^{2} - 11 x - 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 11 ) \pm ( - 11 ) ^{2} - 4 \cdot 10 ( - 8 )}{2 \cdot 10}

(- 11)^{2} - 4 \cdot 10 (- 8) = 21

x_{1, 2} = \frac{- ( - 11 ) \pm 21}{2 \cdot 10}

Separate the solutions

x_{1} = \frac{- ( - 11 ) + 21}{2 \cdot 10}, x_{2} = \frac{- ( - 11 ) - 21}{2 \cdot 10}

x = \frac{- ( - 11 ) + 21}{2 \cdot 10} : \frac{8}{5}

x = \frac{- ( - 11 ) - 21}{2 \cdot 10} : - \frac{1}{2}

The solutions to the quadratic equation are:

x = \frac{8}{5}, x = - \frac{1}{2}

4 w^{2} + 20 w = 0

\frac{8}{3 - x} >> 0

3 (u + 2) - u = 2 (u - 1) + 5

\frac{1}{2} \cdot 0
