k^{2} + 10 k + 15 = 0

k = - 5 + 10, k = - 5 - 10

Decimal Notation

k = - 1.83772 \dots, k = - 8.16227 \dots

Solution steps

k^{2} + 10 k + 15 = 0

Solve with the quadratic formula

k_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 1 \cdot 15}{2 \cdot 1}

1 0^{2} - 4 \cdot 1 \cdot 15 = 210

k_{1, 2} = \frac{- 10 \pm 2 10}{2 \cdot 1}

Separate the solutions

k_{1} = \frac{- 10 + 2 10}{2 \cdot 1}, k_{2} = \frac{- 10 - 2 10}{2 \cdot 1}

k = \frac{- 10 + 2 10}{2 \cdot 1} : - 5 + 10

k = \frac{- 10 - 2 10}{2 \cdot 1} : - 5 - 10

The solutions to the quadratic equation are:

k = - 5 + 10, k = - 5 - 10

s^{2} + 6 s + 25

35 x^{2} + 17 x = - 2

x^{2} + 18 x + 81 = 0

x^{2} + 18 x - 21 = 0

2 x^{2} - 4 x + 4 = 3 x
