- 5 x^{2} + 10 x - 2 = 0

x = \frac{5 - 15}{5}, x = \frac{5 + 15}{5}

Solution steps

- 5 x^{2} + 10 x - 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 ( - 5 ) ( - 2 )}{2 ( - 5 )}

1 0^{2} - 4 (- 5) (- 2) = 215

x_{1, 2} = \frac{- 10 \pm 2 15}{2 ( - 5 )}

Separate the solutions

x_{1} = \frac{- 10 + 2 15}{2 ( - 5 )}, x_{2} = \frac{- 10 - 2 15}{2 ( - 5 )}

x = \frac{- 10 + 2 15}{2 ( - 5 )} : \frac{5 - 15}{5}

x = \frac{- 10 - 2 15}{2 ( - 5 )} : \frac{5 + 15}{5}

The solutions to the quadratic equation are:

x = \frac{5 - 15}{5}, x = \frac{5 + 15}{5}

12 x^{2} + 13 x = 14

x^{2} + 25 x + 36 = 0

9 y (1 - y) = 2

y, y^{2} = x (x - 2) (x + 3)

18 x^{2} - 6 x + 2 = 0
