18 x^{2} + 65 x + 7 = 0

x = - \frac{1}{9}, x = - \frac{7}{2}

Decimal Notation

x = - 0.11111 \dots, x = - 3.5

Solution steps

18 x^{2} + 65 x + 7 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 65 \pm 6 5 ^{2} - 4 \cdot 18 \cdot 7}{2 \cdot 18}

6 5^{2} - 4 \cdot 18 \cdot 7 = 61

x_{1, 2} = \frac{- 65 \pm 61}{2 \cdot 18}

Separate the solutions

x_{1} = \frac{- 65 + 61}{2 \cdot 18}, x_{2} = \frac{- 65 - 61}{2 \cdot 18}

x = \frac{- 65 + 61}{2 \cdot 18} : - \frac{1}{9}

x = \frac{- 65 - 61}{2 \cdot 18} : - \frac{7}{2}

The solutions to the quadratic equation are:

x = - \frac{1}{9}, x = - \frac{7}{2}

\frac{8}{6} + (- \frac{9}{5})

5 x^{2} - 45

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

x + 4 = 3 x - 2

2 x^{2} - 7 x = 15
