0 = x^{2} + 16 x - 5

x = - 8 + 69, x = - 8 - 69

Decimal Notation

x = 0.30662 \dots, x = - 16.30662 \dots

Solution steps

0 = x^{2} + 16 x - 5

Switch sides

x^{2} + 16 x - 5 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 16 \pm 1 6 ^{2} - 4 \cdot 1 \cdot ( - 5 )}{2 \cdot 1}

1 6^{2} - 4 \cdot 1 \cdot (- 5) = 269

x_{1, 2} = \frac{- 16 \pm 2 69}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 16 + 2 69}{2 \cdot 1}, x_{2} = \frac{- 16 - 2 69}{2 \cdot 1}

x = \frac{- 16 + 2 69}{2 \cdot 1} : - 8 + 69

x = \frac{- 16 - 2 69}{2 \cdot 1} : - 8 - 69

The solutions to the quadratic equation are:

x = - 8 + 69, x = - 8 - 69

2 x + 7 = - 11

x^{2} - 27 = 6 x

16 x = 6 x + 100

x^{3} + 3 x^{2} - 25 x - 75

\frac{1}{2} (4)
