x^{2} - 2 x = - 7

x = 1 + 6 i, x = 1 - 6 i

Solution steps

x^{2} - 2 x = - 7

Move

7

to the left side

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

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 2 ) \pm ( - 2 ) ^{2} - 4 \cdot 1 \cdot 7}{2 \cdot 1}

Simplify

(- 2)^{2} - 4 \cdot 1 \cdot 7 : 26 i

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

Separate the solutions

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

x = \frac{- ( - 2 ) + 2 6 i}{2 \cdot 1} : 1 + 6 i

x = \frac{- ( - 2 ) - 2 6 i}{2 \cdot 1} : 1 - 6 i

The solutions to the quadratic equation are:

x = 1 + 6 i, x = 1 - 6 i

3 x^{2} + 2 x - 8 = x^{2} + 2 (x - 2)

x^{2} - \frac{1}{25} = 0

0 = - 2 x^{2} + 9 x - 12

x, y^{3} = 8 x^{2}

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