Use the Principal Axes Theorem to perform a rotation of axes to eliminate the xy-term in the quadratic equation.
2x2 + 4xy + 2y² + 6/2x + 2/2y + 9 = 0
(a) Identify the resulting rotated conic.
ellipse
parabola
O hyperbola
(b) Give its equation in the new coordinate system. (Use xp and yp as the new coordinates.)
4yp“ + 8yp – 4xp + 9 = 0
