- 2 x^{2} + x - 1 = 0

x = \frac{1}{4} - i \frac{7}{4}, x = \frac{1}{4} + i \frac{7}{4}

Solution steps

- 2 x^{2} + x - 1 = 0

Solve with the quadratic formula

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

Simplify

1^{2} - 4 (- 2) (- 1) : 7 i

x_{1, 2} = \frac{- 1 \pm 7 i}{2 ( - 2 )}

Separate the solutions

x_{1} = \frac{- 1 + 7 i}{2 ( - 2 )}, x_{2} = \frac{- 1 - 7 i}{2 ( - 2 )}

x = \frac{- 1 + 7 i}{2 ( - 2 )} : \frac{1}{4} - i \frac{7}{4}

x = \frac{- 1 - 7 i}{2 ( - 2 )} : \frac{1}{4} + i \frac{7}{4}

The solutions to the quadratic equation are:

x = \frac{1}{4} - i \frac{7}{4}, x = \frac{1}{4} + i \frac{7}{4}

4 (x + 2) (x + 3) - 6 x = 12

x^{2} - 6 x - 3

x^{2} - 6 x + 2

2^{2} + 6^{2} = c^{2}

10 x^{2} - 23 x + 12 = 0
