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

x = \frac{9 - 65}{4}, x = \frac{9 + 65}{4}

Decimal Notation

x = 0.23443 \dots, x = 4.26556 \dots

Solution steps

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

Solve with the quadratic formula

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

9^{2} - 4 (- 2) (- 2) = 65

x_{1, 2} = \frac{- 9 \pm 65}{2 ( - 2 )}

Separate the solutions

x_{1} = \frac{- 9 + 65}{2 ( - 2 )}, x_{2} = \frac{- 9 - 65}{2 ( - 2 )}

x = \frac{- 9 + 65}{2 ( - 2 )} : \frac{9 - 65}{4}

x = \frac{- 9 - 65}{2 ( - 2 )} : \frac{9 + 65}{4}

The solutions to the quadratic equation are:

x = \frac{9 - 65}{4}, x = \frac{9 + 65}{4}

z^{2} - 2 z - 24 = 0

(x^{2} - x + 2) = 0

x^{2} - 8 x + 8 = - 4 - 4

3 - 5 x - 2 x^{2} = 0

b^{2} x^{2} - b x = 30
