10 k^{2} + 9 k - 1 = 0

k = \frac{1}{10}, k = - 1

Decimal Notation

k = 0.1, k = - 1

Solution steps

10 k^{2} + 9 k - 1 = 0

Solve with the quadratic formula

k_{1, 2} = \frac{- 9 \pm 9 ^{2} - 4 \cdot 10 ( - 1 )}{2 \cdot 10}

9^{2} - 4 \cdot 10 (- 1) = 11

k_{1, 2} = \frac{- 9 \pm 11}{2 \cdot 10}

Separate the solutions

k_{1} = \frac{- 9 + 11}{2 \cdot 10}, k_{2} = \frac{- 9 - 11}{2 \cdot 10}

k = \frac{- 9 + 11}{2 \cdot 10} : \frac{1}{10}

k = \frac{- 9 - 11}{2 \cdot 10} : - 1

The solutions to the quadratic equation are:

k = \frac{1}{10}, k = - 1

n^{2} = 5 n

x^{2} + 20 x - 60 = 0

w^{2} + 8 w - 48 = 0

r^{2} + 10 r = - 7
