Question

what is the center of the circle with this equation x2+y2+14x-12y=-69

Answer 1

i guess you have to complete squares

Answer 2

x^2 + 14x + 7^2 + y^2 -12y + 6 ^ 2 = -69 + 7^2 + 6^2

since we've already completed squares, we could factor this out

Answer 3

(x+7)^2 + (y-6)^2 = -69 +49 + 36

Answer 4

@lovelaced do you get it ?
now you can solve this
