x^{2} + 11 x + 8 = 0

x = \frac{- 11 + 89}{2}, x = \frac{- 11 - 89}{2}

Decimal Notation

x = - 0.78300 \dots, x = - 10.21699 \dots

Solution steps

x^{2} + 11 x + 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 11 \pm 1 1 ^{2} - 4 \cdot 1 \cdot 8}{2 \cdot 1}

1 1^{2} - 4 \cdot 1 \cdot 8 = 89

x_{1, 2} = \frac{- 11 \pm 89}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 11 + 89}{2 \cdot 1}, x_{2} = \frac{- 11 - 89}{2 \cdot 1}

x = \frac{- 11 + 89}{2 \cdot 1} : \frac{- 11 + 89}{2}

x = \frac{- 11 - 89}{2 \cdot 1} : \frac{- 11 - 89}{2}

The solutions to the quadratic equation are:

x = \frac{- 11 + 89}{2}, x = \frac{- 11 - 89}{2}

\frac{a ^{2}}{4} - ab + b^{2}

(4 x + 3) (5 x + 6) = 0

5 (x + \frac{1}{10}) = 3 x + \frac{1}{2}

2 x yz - 8 z + 14 x y - 56

0 = - 4 x^{2} + 14 x - 7
