Question

write the standard form of the equation x^2-6x+y^2-10y-2=0. find the center

a. (-3,-5)
b.(9,25)
c.(-9,-25)
d.(3,5)

Answer 1

put 2 on the other side
\[x^2 - 6x + y^2 - 10y = 2\]
\[(x^2 - 6x + 9) + (y^2 - 10y + 25) = 2 + 9 + 25\]
\[(x-3)^2 + (y-5)^2 = 36\]
doe that make sense?

Answer 2

Completion Of Square Method..

Answer 3

got it. so the center is (3,5)

Answer 4

yes :D
