0 = 6 x^{2} + 78 x + 216

x = - 4, x = - 9

Solution steps

0 = 6 x^{2} + 78 x + 216

Switch sides

6 x^{2} + 78 x + 216 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 78 \pm 7 8 ^{2} - 4 \cdot 6 \cdot 216}{2 \cdot 6}

7 8^{2} - 4 \cdot 6 \cdot 216 = 30

x_{1, 2} = \frac{- 78 \pm 30}{2 \cdot 6}

Separate the solutions

x_{1} = \frac{- 78 + 30}{2 \cdot 6}, x_{2} = \frac{- 78 - 30}{2 \cdot 6}

x = \frac{- 78 + 30}{2 \cdot 6} : - 4

x = \frac{- 78 - 30}{2 \cdot 6} : - 9

The solutions to the quadratic equation are:

x = - 4, x = - 9

5 x + 3 \leq - 72 or 3 x + 1 > - 14

\frac{3}{2} ln (x - y) - 2 ln (x^{2} + y^{2})

\frac{9}{8} + \frac{8}{9}

x^{2} + x y - 2 y^{2}
