If a ≠ 0 and the line 2bx + 3cy + 4d = 0 passes through the points of intersection of the parabolas y2 = 4ax and x2 = 4ay, then-
Text Solution
Verified by ExpertsThe correct answer is:
D
The two parabolas intersect at (0, 0) and (4a, 4a). The equation of their common chord must be y = x which must be same as given line
2bx + 3ay + 4d = 0
⇒ 2b = – 3c, d = 0
⇒ (2b + 3c)2 + d2 = 0
