Donde Xo = 4; Yo = 2;
a = 9 - 4 = 5 Semi eje mayor; a² = 25
c = 7 - 4 = 3 Distancia del centro al foco c² = 9
b = ; b² = 16
[(X - 4)²]/25 + [(Y - 2)²]/16 = 1: Ecuacion Canonica
(X² - 8X + 16)/25 + (Y² - 4Y + 4)/16 = 1 (Comun denominador de 25 y 16) 400
16(X² - 8X + 16) + 25(Y² - 4Y + 4) = 400
16X² - 128X + 256 + 25Y² - 100Y + 100 = 400
16X² + 25Y² - 128X - 100Y = 400 - 256 - 100
16X² + 25Y² - 128X - 100Y = 44
16X² + 25Y² - 128X - 100Y - 44 = 0 Ecuacion General
