x^{2} - 2 x - 2 + 8 = 0

x = 1 + 5 i, x = 1 - 5 i

Solution steps

x^{2} - 2 x - 2 + 8 = 0

Refine

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

Solve with the quadratic formula

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

Simplify

(- 2)^{2} - 4 \cdot 1 \cdot 6 : 25 i

x_{1, 2} = \frac{- ( - 2 ) \pm 2 5 i}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 2 ) + 2 5 i}{2 \cdot 1}, x_{2} = \frac{- ( - 2 ) - 2 5 i}{2 \cdot 1}

x = \frac{- ( - 2 ) + 2 5 i}{2 \cdot 1} : 1 + 5 i

x = \frac{- ( - 2 ) - 2 5 i}{2 \cdot 1} : 1 - 5 i

The solutions to the quadratic equation are:

x = 1 + 5 i, x = 1 - 5 i

4 m^{2} - m - 3 = - m^{2}

20 x^{2} - x = 30

x^{3} - 3 x + 2 = (x + a)^{2} (x + b)

(2 x + 3) (3 x - 1) = 0

4 x^{2} - 40 x + 109 = 0
