x^{2} - 9 x = - 2 x - 6

x = 6, x = 1

Solution steps

x^{2} - 9 x = - 2 x - 6

Move

6

to the left side

x^{2} - 9 x + 6 = - 2 x

Move

2 x

to the left side

x^{2} - 7 x + 6 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 \cdot 1 \cdot 6}{2 \cdot 1}

(- 7)^{2} - 4 \cdot 1 \cdot 6 = 5

x_{1, 2} = \frac{- ( - 7 ) \pm 5}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 7 ) + 5}{2 \cdot 1}, x_{2} = \frac{- ( - 7 ) - 5}{2 \cdot 1}

x = \frac{- ( - 7 ) + 5}{2 \cdot 1} : 6

x = \frac{- ( - 7 ) - 5}{2 \cdot 1} : 1

The solutions to the quadratic equation are:

x = 6, x = 1

- \frac{1}{3} + \frac{1}{9}

(5^{- 6})^{- 4}

6 + 6 x - 10 = - 20

- 7 x + 6 x \leq - 4

96 b^{2} = 6
