2 y^{2} + 5 y + 2 = 0

y = - \frac{1}{2}, y = - 2

Decimal Notation

y = - 0.5, y = - 2

Solution steps

2 y^{2} + 5 y + 2 = 0

Solve with the quadratic formula

y_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 \cdot 2 \cdot 2}{2 \cdot 2}

5^{2} - 4 \cdot 2 \cdot 2 = 3

y_{1, 2} = \frac{- 5 \pm 3}{2 \cdot 2}

Separate the solutions

y_{1} = \frac{- 5 + 3}{2 \cdot 2}, y_{2} = \frac{- 5 - 3}{2 \cdot 2}

y = \frac{- 5 + 3}{2 \cdot 2} : - \frac{1}{2}

y = \frac{- 5 - 3}{2 \cdot 2} : - 2

The solutions to the quadratic equation are:

y = - \frac{1}{2}, y = - 2

\frac{3 x - 2}{x + 1} + 4 > 0
