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

x = - \frac{1}{2} + i \frac{7}{2}, x = - \frac{1}{2} - i \frac{7}{2}

Solution steps

x^{2} + 1 \cdot x + 2 = 0

Refine

x^{2} + x + 2 = 0

Solve with the quadratic formula

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

Simplify

1^{2} - 4 \cdot 1 \cdot 2 : 7 i

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

Separate the solutions

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

x = \frac{- 1 + 7 i}{2 \cdot 1} : - \frac{1}{2} + i \frac{7}{2}

x = \frac{- 1 - 7 i}{2 \cdot 1} : - \frac{1}{2} - i \frac{7}{2}

The solutions to the quadratic equation are:

x = - \frac{1}{2} + i \frac{7}{2}, x = - \frac{1}{2} - i \frac{7}{2}

x^{2} - 15 x - 2 = 0

x^{2} + 30 x - 7000 = 0

2 x^{2} + 18 = 10

3 x^{2} + 9 x = 0

k, f = k x^{3} + x^{2} + k^{2} x + 3 k^{2} + 11
