-x^2+3x+18=0

Solution

- x^{2} + 3 x + 18 = 0

Solution

x = - 3, x = 6

Solution steps

- x^{2} + 3 x + 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 ( - 1 ) \cdot 18}{2 ( - 1 )}

3^{2} - 4 (- 1) \cdot 18 = 9

x_{1, 2} = \frac{- 3 \pm 9}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 3 + 9}{2 ( - 1 )}, x_{2} = \frac{- 3 - 9}{2 ( - 1 )}

x = \frac{- 3 + 9}{2 ( - 1 )} : - 3

x = \frac{- 3 - 9}{2 ( - 1 )} : 6

The solutions to the quadratic equation are:

x = - 3, x = 6
