Answer:
67
Step-by-step explanation:

72
Answer:
D
Step-by-step explanation:
Given a quadratic equation in standard form : ax² + bx + c = 0
We can solve for x using the quadratic formula
x² + 2x + 9 = 0 ← is in standard form
with a = 1, b = 2 and c = 9
x = ( - 2 ±
) / 2
= ( - 2 ±
) / 2
= (- 2±
) / 2)
= (- 2 ±
) / 2
= ( - 2 ± 4i
) / 2
=
± 
= - 1 ± 2i
→ D
