10 x^{2} - 15 x - \frac{17}{5} = 0

x = \frac{17}{10}, x = - \frac{1}{5}

Solution steps

10 x^{2} - 15 x - \frac{17}{5} = 0

Multiply both sides by

5

50 x^{2} - 75 x - 17 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 75 ) \pm ( - 75 ) ^{2} - 4 \cdot 50 ( - 17 )}{2 \cdot 50}

(- 75)^{2} - 4 \cdot 50 (- 17) = 95

x_{1, 2} = \frac{- ( - 75 ) \pm 95}{2 \cdot 50}

Separate the solutions

x_{1} = \frac{- ( - 75 ) + 95}{2 \cdot 50}, x_{2} = \frac{- ( - 75 ) - 95}{2 \cdot 50}

x = \frac{- ( - 75 ) + 95}{2 \cdot 50} : \frac{17}{10}

x = \frac{- ( - 75 ) - 95}{2 \cdot 50} : - \frac{1}{5}

The solutions to the quadratic equation are:

x = \frac{17}{10}, x = - \frac{1}{5}

lo g_{3} (729)

x \leq 3 - \frac{6}{x + 2}

\frac{n + 1}{6} + \frac{n + 1}{2} = 7

7 a - 8 = 24 + 3 a

\frac{4 y}{9} - \frac{3 y}{4} + 12 < 11
