Question

(x^2+12x )+(y^2-18y )=5 Complete the square on x by adding?

Answer 1

(x^2+12x) + (y^2-18y) = 5

=> (x^2+12x) + 36 + (y^2-18y) + 81 = 5 +36 + 81

=> (x^2+12x+36) + (y^2-18y+81) = 122

=> (x^2 + 2×x×6 + 6^2) + (y^2 - 2×y×9 + 9^2) = 122

=> (x + 6)^2 + (y - 9)^2 = 122

Answer 2

if your just factoring out then this should help   x2 + 12x + y2 - 18y if they want something else i'm sorry
