Question 184

Multiple Choice

Write Equations of Rotated Conics in Standard Form
- x2+2xy+y2+xy4=0x ^ { 2 } + 2 x y + y ^ { 2 } + x - y - 4 = 0


A) x2=22y+2x ^ { \prime 2 } = \frac { \sqrt { 2 } } { 2 } y ^ { \prime } + 2
B) y2=22xy ^ { \prime 2 } = \frac { \sqrt { 2 } } { 2 } x ^ { \prime }
C) x22+y24=1\frac { x ^ { \prime 2 } } { 2 } + \frac { y ^ { \prime 2 } } { 4 } = 1
D) x22y24=1\frac { x ^ { \prime 2 } } { 2 } - \frac { y ^ { \prime 2 } } { 4 } = 1
