A horizontal eclipse has a major axis of length 40 and a minor axis of length 24. If its center is at origin, write the equation of the eclipse in standard form. Graph the eclipse.

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
