6 x^{2} + 72 x + 210 = 0

x = - 5, x = - 7

Solution steps

6 x^{2} + 72 x + 210 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 72 \pm 7 2 ^{2} - 4 \cdot 6 \cdot 210}{2 \cdot 6}

7 2^{2} - 4 \cdot 6 \cdot 210 = 12

x_{1, 2} = \frac{- 72 \pm 12}{2 \cdot 6}

Separate the solutions

x_{1} = \frac{- 72 + 12}{2 \cdot 6}, x_{2} = \frac{- 72 - 12}{2 \cdot 6}

x = \frac{- 72 + 12}{2 \cdot 6} : - 5

x = \frac{- 72 - 12}{2 \cdot 6} : - 7

The solutions to the quadratic equation are:

x = - 5, x = - 7

- \frac{1}{2} < \frac{4 - 3 x}{5} < \frac{1}{4}

3 x^{2} - x - 7 = 0

x^{2} + 9 x + 8 = 0

x^{2} - 4 x = - 8

- 3 x + 22 < 16
