If the quadratic equation x^2 + 6x + 9 = 0 is represented graphically, what type of intersection doe

A. Two distinct points

B. One point (tangent)

C. No intersection

D. Infinite points

E. None of the above

Answer: B. One point (tangent)

The equation can be factored as (x + 3)(x + 3) = 0, indicating a double root at x = -3, which means it touches the x-axis at one point.
