- 2 x^{2} + 6 x - 9 = 0

x = \frac{3}{2} - i \frac{3}{2}, x = \frac{3}{2} + i \frac{3}{2}

Solution steps

- 2 x^{2} + 6 x - 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 ( - 2 ) ( - 9 )}{2 ( - 2 )}

Simplify

6^{2} - 4 (- 2) (- 9) : 6 i

x_{1, 2} = \frac{- 6 \pm 6 i}{2 ( - 2 )}

Separate the solutions

x_{1} = \frac{- 6 + 6 i}{2 ( - 2 )}, x_{2} = \frac{- 6 - 6 i}{2 ( - 2 )}

x = \frac{- 6 + 6 i}{2 ( - 2 )} : \frac{3}{2} - i \frac{3}{2}

x = \frac{- 6 - 6 i}{2 ( - 2 )} : \frac{3}{2} + i \frac{3}{2}

The solutions to the quadratic equation are:

x = \frac{3}{2} - i \frac{3}{2}, x = \frac{3}{2} + i \frac{3}{2}

x, z = 6 - x^{2} - y^{2}

(k - 1) x^{2} + k^{2} x + 21 = 0

6 x^{2} = 10 + 11 x

x, x^{2} - 16 x = 5 x - 9

3 x^{2} - 18 x + 7 = 0
