Question 87

Multiple Choice

Find the center and foci of the following ellipse.
4x2+8y216x+32y+32=04 x ^ { 2 } + 8 y ^ { 2 } - 16 x + 32 y + 32 = 0


A) Center: (2,2) ( - 2,2 )
Foci: (2+2,2) ,(22,2) ( - 2 + \sqrt { 2 } , 2 ) , ( - 2 - \sqrt { 2 } , 2 )
B) Center: (2,2) ( 2 , - 2 )
Foci: (2+2,2) ,(22,2) ( 2 + \sqrt { 2 } , - 2 ) , ( 2 - \sqrt { 2 } , - 2 )
C) Center: (2,2) ( 2 , - 2 )
Foci: (2,2+2) ,(2,22) ( 2 , - 2 + \sqrt { 2 } ) , ( 2 , - 2 - \sqrt { 2 } )
D) Center: (2,2) ( - 2,2 )
Foci: (2,2+2) ,(2,22) ( - 2,2 + \sqrt { 2 } ) , ( - 2,2 - \sqrt { 2 } )
E) Center: (2,2) ( - 2,2 )
Foci: (2+6,2) ,(26,2) ( - 2 + \sqrt { 6 } , 2 ) , ( - 2 - \sqrt { 6 } , - 2 )
