6 x^{2} + 30 x - 84 = 0

x = 2, x = - 7

Solution steps

6 x^{2} + 30 x - 84 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 30 \pm 3 0 ^{2} - 4 \cdot 6 ( - 84 )}{2 \cdot 6}

3 0^{2} - 4 \cdot 6 (- 84) = 54

x_{1, 2} = \frac{- 30 \pm 54}{2 \cdot 6}

Separate the solutions

x_{1} = \frac{- 30 + 54}{2 \cdot 6}, x_{2} = \frac{- 30 - 54}{2 \cdot 6}

x = \frac{- 30 + 54}{2 \cdot 6} : 2

x = \frac{- 30 - 54}{2 \cdot 6} : - 7

The solutions to the quadratic equation are:

x = 2, x = - 7

\frac{- 65 \cdot 6}{65}

\frac{3 x ^{2} - 15 x + 18}{3 x - 9}

4 x - 7 = - 15

1 - 25 x^{2}

2 x^{2} - 27 x + 36
