Question

The equation of a circle is x2 + y2 + 6x + 4y + 10 = 1. What is this equation written in its standard form?

A) (x + 3)2 + (y + 2)2 = 4
B) (x + 6)2 + (y + 4)2 = 4
C) (x + 6)2 + (y + 4)2 = 10
D) (x + 3)2 + (y + 2)2 = 10

Answer 1

the answer is A

Explanation:

i hope i helped you out

Answer 2

answer : A

Explanation:

hello :

x² + y² + 6x + 4y + 10 = 1

(x² + 6x )+(y²+ 4y) + 10 = 1

(x² + 6x+9-9 )+(y²+ 4y+4-4) + 10 = 1

(x² + 6x+9)-9 +(y²+ 4y+4)-4 + 10 = 1

(x+3)²+(y+2)² = 4 answer : A
