Question

what are the coordinates of the center of the circle shown below? x^2+y^2 -8x -10y-8

Answer 1

4,5

Answer 2

group all the x and y firs \[(x^2 -8x) + (y^2 - 10y) = 8\] now complete the square of each group

@NotSObright mind backing up your answer? /:)

Answer 3

(x^2-8x+16)+(y^2-10y+100)-16-100-8=0
(x-4)^2+(y-5)^2=124

Answer 4

thank you guys
