Step-by-step explanation:
standard form = 
now, when circle passes through (3,-1);
⇒ 
⇒
...............( equation 1)
when circle passes through (-2,4);
⇒ 
⇒
...............( equation 2)
when circle passes through (6,8);
⇒ 
⇒
................( equation 3)
by solving these 3 equations , we get;
D = -6, E = -8, F = 0
hence,
standard form = 
= 
Answer:
