3 x^{2} + 24 x + 9 = 0

x = - 4 + 13, x = - 4 - 13

Decimal Notation

x = - 0.39444 \dots, x = - 7.60555 \dots

Solution steps

3 x^{2} + 24 x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 24 \pm 2 4 ^{2} - 4 \cdot 3 \cdot 9}{2 \cdot 3}

2 4^{2} - 4 \cdot 3 \cdot 9 = 613

x_{1, 2} = \frac{- 24 \pm 6 13}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- 24 + 6 13}{2 \cdot 3}, x_{2} = \frac{- 24 - 6 13}{2 \cdot 3}

x = \frac{- 24 + 6 13}{2 \cdot 3} : - 4 + 13

x = \frac{- 24 - 6 13}{2 \cdot 3} : - 4 - 13

The solutions to the quadratic equation are:

x = - 4 + 13, x = - 4 - 13

x^{2} + 5 x - 14 \leq 0

3 x^{2} + 5 x - 2 < 0

12 x^{2} + 13 x = 4

\frac{3}{4} + \frac{1}{6} - \frac{2}{3}

12 x^{2} + 11 x + 2
