5 x^{2} - 9 x - 2 = 0

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

Decimal Notation

x = 2, x = - 0.2

Solution steps

5 x^{2} - 9 x - 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 5 ( - 2 )}{2 \cdot 5}

(- 9)^{2} - 4 \cdot 5 (- 2) = 11

x_{1, 2} = \frac{- ( - 9 ) \pm 11}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 9 ) + 11}{2 \cdot 5}, x_{2} = \frac{- ( - 9 ) - 11}{2 \cdot 5}

x = \frac{- ( - 9 ) + 11}{2 \cdot 5} : 2

x = \frac{- ( - 9 ) - 11}{2 \cdot 5} : - \frac{1}{5}

The solutions to the quadratic equation are:

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

\frac{b ^{2} - 2 b - 8}{b ^{2} + b - 2} - \frac{6}{b - 1}

5 \cdot 4

32 - 50

5 x - 8 = 3 x - 9

3 y + 4 (y + 3) - 5 (1 - 2 y) = 1 - 4 (5 y - 2) - 4 y - 1
