If \((h, k)\) be the point to which the origin has to be shifted in order to get the transformed equation of \(y^2-4 x+6 y+17=0\) as \(y^2=4 a x\), then \(h^2+k^2=\)
- A 11
- B 1
- C 25
- D 13
Answer & Solution
Correct Answer
(D) 13
Step-by-step Solution
Detailed explanation
Given equation is \(y^2-4 x+6 y+17=0\) \(\Rightarrow \quad(y+3)^2=4(x-2)\) If origin is shifted to the point \((2,-3)\), then the equation \(y^2-4 x+6 y+17=0\) get transformed as \(y^2=4 a x\). So, \(\quad(h, k)=(2,-3)\) \(\therefore h^2+k^2=4+9=13\) Hence, option (d) is correct.
