2 x^{2} + 17 x - 9 = 0

x = \frac{1}{2}, x = - 9

Decimal Notation

x = 0.5, x = - 9

Solution steps

2 x^{2} + 17 x - 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 17 \pm 1 7 ^{2} - 4 \cdot 2 ( - 9 )}{2 \cdot 2}

1 7^{2} - 4 \cdot 2 (- 9) = 19

x_{1, 2} = \frac{- 17 \pm 19}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 17 + 19}{2 \cdot 2}, x_{2} = \frac{- 17 - 19}{2 \cdot 2}

x = \frac{- 17 + 19}{2 \cdot 2} : \frac{1}{2}

x = \frac{- 17 - 19}{2 \cdot 2} : - 9

The solutions to the quadratic equation are:

x = \frac{1}{2}, x = - 9

- 3 x x_{+} 5 (x - 2)

- 2 x = 10
