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= )
Options
- A11
- B1
- C25
- D13
Correct answer
D. 13
Step-by-step solution
Given equation is (y^2-4 x+6 y+17=0 ) ( (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, ( (h, k)=(2,-3) ) ( h^2+k^2=4+9=13 ) Hence, option (d) is correct.
