-x^2-8x-12=0

Solution

- x^{2} - 8 x - 12 = 0

Solution

x = - 6, x = - 2

Solution steps

- x^{2} - 8 x - 12 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 ( - 1 ) ( - 12 )}{2 ( - 1 )}

(- 8)^{2} - 4 (- 1) (- 12) = 4

x_{1, 2} = \frac{- ( - 8 ) \pm 4}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- ( - 8 ) + 4}{2 ( - 1 )}, x_{2} = \frac{- ( - 8 ) - 4}{2 ( - 1 )}

x = \frac{- ( - 8 ) + 4}{2 ( - 1 )} : - 6

x = \frac{- ( - 8 ) - 4}{2 ( - 1 )} : - 2

The solutions to the quadratic equation are:

x = - 6, x = - 2
