- 2 x^{2} + 7 x + 30 = 0

x = - \frac{5}{2}, x = 6

Solution steps

- 2 x^{2} + 7 x + 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 ( - 2 ) \cdot 30}{2 ( - 2 )}

7^{2} - 4 (- 2) \cdot 30 = 17

x_{1, 2} = \frac{- 7 \pm 17}{2 ( - 2 )}

Separate the solutions

x_{1} = \frac{- 7 + 17}{2 ( - 2 )}, x_{2} = \frac{- 7 - 17}{2 ( - 2 )}

x = \frac{- 7 + 17}{2 ( - 2 )} : - \frac{5}{2}

x = \frac{- 7 - 17}{2 ( - 2 )} : 6

The solutions to the quadratic equation are:

x = - \frac{5}{2}, x = 6

\frac{3}{14} \cdot \frac{4}{6}

\frac{5}{28} = \frac{h}{32}

x^{2} + 6 x - 1 = - 7

3 x - 5 < - 17 and - 6 x + 5 > 11

2 s^{2} - 11 s + 5
