F (x) = 3x² + 3x + 9

3x² + 3x + 9 = 0

x = - (3) + / - √ ((3) ² - 4 (3) (9))

2 (3)

x = - 3 + / - √ (9 - 108)

6

x = - 3 + / - √ (99)

6

x = - 3 + / - 3√ (11)

6

x = - 0.5 + 0.5√ (11)

x = - 0.5 + 0.5√ (11) x = - 0.5 - 0.5√ (11)

Select the approximate values of x that are solutions to f (x) = 0, wheref (x) = - 3x2 + 3x + 9.
