2 x^{2} + 9 x + 9 = 0

x = - \frac{3}{2}, x = - 3

Decimal Notation

x = - 1.5, x = - 3

Solution steps

2 x^{2} + 9 x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 9 \pm 9 ^{2} - 4 \cdot 2 \cdot 9}{2 \cdot 2}

9^{2} - 4 \cdot 2 \cdot 9 = 3

x_{1, 2} = \frac{- 9 \pm 3}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 9 + 3}{2 \cdot 2}, x_{2} = \frac{- 9 - 3}{2 \cdot 2}

x = \frac{- 9 + 3}{2 \cdot 2} : - \frac{3}{2}

x = \frac{- 9 - 3}{2 \cdot 2} : - 3

The solutions to the quadratic equation are:

x = - \frac{3}{2}, x = - 3

3 x^{4} + 6 x^{3} + 3 x^{2} + 24 x - 36

p^{2} - 10 p + 24 = 0
