Question:
Combined equation to the pair of tangents drawn from the origin to the circle <span class="math-inline">\(x^2 + y^2 + 4x + 6y + 9 = 0\)</span> is
3(x^2 + y^2) = (x + 2y)^2
2(x^2 + y^2) = (3x + y)^2
9(x^2 + y^2) = (2x + 3y)^2
x^2 + y^2 = (2x + 3y)^2
Step-by-Step Solution
Key Concept: General
The area of the triangle formed by three points on a parabola is twice the area of the triangle formed by the tangents at these points.
Correct Answer: 2
