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

k = \frac{- 5 + 89}{2}, k = \frac{- 5 - 89}{2}

Decimal Notation

k = 2.21699 \dots, k = - 7.21699 \dots

Solution steps

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

Solve with the quadratic formula

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

5^{2} - 4 \cdot 1 \cdot (- 16) = 89

k_{1, 2} = \frac{- 5 \pm 89}{2 \cdot 1}

Separate the solutions

k_{1} = \frac{- 5 + 89}{2 \cdot 1}, k_{2} = \frac{- 5 - 89}{2 \cdot 1}

k = \frac{- 5 + 89}{2 \cdot 1} : \frac{- 5 + 89}{2}

k = \frac{- 5 - 89}{2 \cdot 1} : \frac{- 5 - 89}{2}

The solutions to the quadratic equation are:

k = \frac{- 5 + 89}{2}, k = \frac{- 5 - 89}{2}

x + 4 \leq 13

(\frac{1}{2})^{20}

- x \leq 15 - 2 x
