- 5 k^{2} - 8 k + 3 = 0

k = - \frac{4 + 31}{5}, k = \frac{31 - 4}{5}

Solution steps

- 5 k^{2} - 8 k + 3 = 0

Solve with the quadratic formula

k_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 ( - 5 ) \cdot 3}{2 ( - 5 )}

(- 8)^{2} - 4 (- 5) \cdot 3 = 231

k_{1, 2} = \frac{- ( - 8 ) \pm 2 31}{2 ( - 5 )}

Separate the solutions

k_{1} = \frac{- ( - 8 ) + 2 31}{2 ( - 5 )}, k_{2} = \frac{- ( - 8 ) - 2 31}{2 ( - 5 )}

k = \frac{- ( - 8 ) + 2 31}{2 ( - 5 )} : - \frac{4 + 31}{5}

k = \frac{- ( - 8 ) - 2 31}{2 ( - 5 )} : \frac{31 - 4}{5}

The solutions to the quadratic equation are:

k = - \frac{4 + 31}{5}, k = \frac{31 - 4}{5}

\frac{4}{5} (\frac{3}{4} - \frac{3}{6})

70 - a \geq 25

\frac{( \frac{48.57983 + 48.57983}{9.8} )}{2}

\frac{49}{3} - 10

- 5 (- x - 3) - x + 2 = 11
