0 = x^{2} + 8 x + 5

x = - 4 + 11, x = - 4 - 11

Decimal Notation

x = - 0.68337 \dots, x = - 7.31662 \dots

Solution steps

0 = x^{2} + 8 x + 5

Switch sides

x^{2} + 8 x + 5 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 1 \cdot 5}{2 \cdot 1}

8^{2} - 4 \cdot 1 \cdot 5 = 211

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

Separate the solutions

x_{1} = \frac{- 8 + 2 11}{2 \cdot 1}, x_{2} = \frac{- 8 - 2 11}{2 \cdot 1}

x = \frac{- 8 + 2 11}{2 \cdot 1} : - 4 + 11

x = \frac{- 8 - 2 11}{2 \cdot 1} : - 4 - 11

The solutions to the quadratic equation are:

x = - 4 + 11, x = - 4 - 11

x^{2} + 58 = 9

x^{2} - 14 x + 62 = - 77

25 (1 - 4 x)^{2} - 28 = - 12

x^{2} - 4 x = 4 x

(x - 3)^{2} = \frac{x ^{2} - 9}{3}
