TS EAMCET · Maths · Parabola
The equation of the parabola with the focus \((3,0)\) and the directrix \(x+3=0\), is.
- A \(y^2=3 x\)
- B \(y^2=6 x\)
- C \(y^2=12 x\)
- D \(y^2=2 x\)
Answer & Solution
Correct Answer
(C) \(y^2=12 x\)
Step-by-step Solution
Detailed explanation
Given that focus is \(S(3,0)\), let \(P(x, y)\) be any point on the parabola. \(\therefore\) Directrix is, \(x+3=0\) Also, \(S P^2=P M^2\)…
