x^{2} - 2 x = - 9

x = 1 + 22 i, x = 1 - 22 i

Solution steps

x^{2} - 2 x = - 9

Move

9

to the left side

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

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 2 ) \pm ( - 2 ) ^{2} - 4 \cdot 1 \cdot 9}{2 \cdot 1}

Simplify

(- 2)^{2} - 4 \cdot 1 \cdot 9 : 42 i

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

Separate the solutions

x_{1} = \frac{- ( - 2 ) + 4 2 i}{2 \cdot 1}, x_{2} = \frac{- ( - 2 ) - 4 2 i}{2 \cdot 1}

x = \frac{- ( - 2 ) + 4 2 i}{2 \cdot 1} : 1 + 22 i

x = \frac{- ( - 2 ) - 4 2 i}{2 \cdot 1} : 1 - 22 i

The solutions to the quadratic equation are:

x = 1 + 22 i, x = 1 - 22 i

9 (y - 1)^{2} - 25

12 x^{3} - 9 x^{2} - 4 x + 3

\frac{x - 2}{3} < 4

\frac{2 x + 7}{3} = \frac{4 x + 5}{2}

10 x + 4 x y - 18 x y^{2}
