6 x^{2} - 12 x - 90 = 0

x = 5, x = - 3

Solution steps

6 x^{2} - 12 x - 90 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 12 ) \pm ( - 12 ) ^{2} - 4 \cdot 6 ( - 90 )}{2 \cdot 6}

(- 12)^{2} - 4 \cdot 6 (- 90) = 48

x_{1, 2} = \frac{- ( - 12 ) \pm 48}{2 \cdot 6}

Separate the solutions

x_{1} = \frac{- ( - 12 ) + 48}{2 \cdot 6}, x_{2} = \frac{- ( - 12 ) - 48}{2 \cdot 6}

x = \frac{- ( - 12 ) + 48}{2 \cdot 6} : 5

x = \frac{- ( - 12 ) - 48}{2 \cdot 6} : - 3

The solutions to the quadratic equation are:

x = 5, x = - 3
