Answer:
Step-by-step explanation:
Let p ( x ) = 3x² + x + 6 = 0
Comparing the given equation with ax²+ bx + c = 0,
We have a = 3 , b = 1 and c= 6.
∴Discriminant = d = b² - 4ac = ( 1 )² - 4 ( 3 ) ( 6 ) = 1 - 72 = - 71.
∴ x = - b ± √ b² - 4ac / 2a
= - 1 ± √ - 71 / 2 ( 3 )
= - 1 ± √- 71 / 6 is the answer.
