Question

Put the equation is standard form x^2+y^2+16x-8y+76=0

Answer 1

-8, 4, 2

Explanation:

x^2 + y^2 + 16x - 8y + 76 = 0

x^2 + y^2 + 16x - 8y = -76

x^2 + 16x + y^2 - 8y = -76

x^2 + 16x + ? + y^2 - 8y = -76 + ?

x^2 + 16x + 64 + y^2 - 8y = -76 + 64

(x + 8)^2 + y^2 - 8y = -12

(x + 8)^2 + y^2 - 8y + ? = -12 + ?

(x + 8)^2 + y^2 - 8y + 16 = -12 + 16

(x + 8)^2 + (y - 4)^2 = 4

(x + (-8))^2 + (y - 4)^2 = 2^2

Answer 2

( x + 8 )^ 2 + ( y − 4 ) ^2 =4
