- 2 x^{2} + 36 x - 170 = 0

x = 9 - 2 i, x = 9 + 2 i

Solution steps

- 2 x^{2} + 36 x - 170 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 36 \pm 3 6 ^{2} - 4 ( - 2 ) ( - 170 )}{2 ( - 2 )}

Simplify

3 6^{2} - 4 (- 2) (- 170) : 8 i

x_{1, 2} = \frac{- 36 \pm 8 i}{2 ( - 2 )}

Separate the solutions

x_{1} = \frac{- 36 + 8 i}{2 ( - 2 )}, x_{2} = \frac{- 36 - 8 i}{2 ( - 2 )}

x = \frac{- 36 + 8 i}{2 ( - 2 )} : 9 - 2 i

x = \frac{- 36 - 8 i}{2 ( - 2 )} : 9 + 2 i

The solutions to the quadratic equation are:

x = 9 - 2 i, x = 9 + 2 i

4 x^{2} - 12 x + 7 = 0

4 x^{2} + 3 = 4 x

x^{2} + 2 x = - 20

14 x^{2} - 21 x = 0

- 8 x^{2} + 5 = - 4 x
