2 x^{2} + 5 x - 18 = 0

x = 2, x = - \frac{9}{2}

Solution steps

2 x^{2} + 5 x - 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 \cdot 2 ( - 18 )}{2 \cdot 2}

5^{2} - 4 \cdot 2 (- 18) = 13

x_{1, 2} = \frac{- 5 \pm 13}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 5 + 13}{2 \cdot 2}, x_{2} = \frac{- 5 - 13}{2 \cdot 2}

x = \frac{- 5 + 13}{2 \cdot 2} : 2

x = \frac{- 5 - 13}{2 \cdot 2} : - \frac{9}{2}

The solutions to the quadratic equation are:

x = 2, x = - \frac{9}{2}

\frac{3}{5} \geq \frac{2}{5}
