- 9 - x + x^{2} = - 5 x

x = - 2 + 13, x = - 2 - 13

Decimal Notation

x = 1.60555 \dots, x = - 5.60555 \dots

Solution steps

- 9 - x + x^{2} = - 5 x

Move

5 x

to the left side

x^{2} + 4 x - 9 = 0

Solve with the quadratic formula

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

4^{2} - 4 \cdot 1 \cdot (- 9) = 213

x_{1, 2} = \frac{- 4 \pm 2 13}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 4 + 2 13}{2 \cdot 1}, x_{2} = \frac{- 4 - 2 13}{2 \cdot 1}

x = \frac{- 4 + 2 13}{2 \cdot 1} : - 2 + 13

x = \frac{- 4 - 2 13}{2 \cdot 1} : - 2 - 13

The solutions to the quadratic equation are:

x = - 2 + 13, x = - 2 - 13

- 6 x^{2} - 4 x - 1 = 0

v^{2} + v - 4 = 0

(x - 4)^{2} = 24

x^{2} = 3 2^{2} + 2 4^{2}

7 x^{2} + 14 x = 0
