0 = - \frac{1}{2} x^{2} + 6 x - 18

x = 6

Solution steps

0 = - \frac{1}{2} x^{2} + 6 x - 18

Multiply both sides by

2

0 = - x^{2} + 12 x - 36

Switch sides

- x^{2} + 12 x - 36 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 12 \pm 1 2 ^{2} - 4 ( - 1 ) ( - 36 )}{2 ( - 1 )}

1 2^{2} - 4 (- 1) (- 36) = 0

x_{1, 2} = \frac{- 12 \pm 0}{2 ( - 1 )}

x = \frac{- 12}{2 ( - 1 )}

\frac{- 12}{2 ( - 1 )} = 6

x = 6

The solution to the quadratic equation is:

x = 6

- 19 \geq - 20 + v

- 56 = d + 23

- 7 x < 56

x < - 6 and x > 2
