7 k^{2} + 57 k + 8 = 0

k = - \frac{1}{7}, k = - 8

Solution steps

7 k^{2} + 57 k + 8 = 0

Solve with the quadratic formula

k_{1, 2} = \frac{- 57 \pm 5 7 ^{2} - 4 \cdot 7 \cdot 8}{2 \cdot 7}

5 7^{2} - 4 \cdot 7 \cdot 8 = 55

k_{1, 2} = \frac{- 57 \pm 55}{2 \cdot 7}

Separate the solutions

k_{1} = \frac{- 57 + 55}{2 \cdot 7}, k_{2} = \frac{- 57 - 55}{2 \cdot 7}

k = \frac{- 57 + 55}{2 \cdot 7} : - \frac{1}{7}

k = \frac{- 57 - 55}{2 \cdot 7} : - 8

The solutions to the quadratic equation are:

k = - \frac{1}{7}, k = - 8

0 = - 16 t^{2} + 32 t + 8

x^{2} + 4 x - 96 = 0
