- x^{2} + 10 x + 9 = 0

x = 5 - 34, x = 5 + 34

Decimal Notation

x = - 0.83095 \dots, x = 10.83095 \dots

Solution steps

- x^{2} + 10 x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 ( - 1 ) \cdot 9}{2 ( - 1 )}

1 0^{2} - 4 (- 1) \cdot 9 = 234

x_{1, 2} = \frac{- 10 \pm 2 34}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 10 + 2 34}{2 ( - 1 )}, x_{2} = \frac{- 10 - 2 34}{2 ( - 1 )}

x = \frac{- 10 + 2 34}{2 ( - 1 )} : 5 - 34

x = \frac{- 10 - 2 34}{2 ( - 1 )} : 5 + 34

The solutions to the quadratic equation are:

x = 5 - 34, x = 5 + 34

10.36 + 0.131 \cdot 12 + 0.21 \cdot 12

- (x - 4) + 8 x - 7 - 2 (x - 2) = - 8 x - 5 (7 - x) + 2 x

26 = x
