CAPITULO II

Resta de polinomios con coeficientes fraccionarios
Ejercicio 25
  • Se identifican tanto el minuendo como sustraendo
  • Se escribe el minuendo con su propio signo, cambiamos de signo a cada uno de los términos del sustraendo y ordenamos si fuese el caso
  • Se reduce términos semejantes
Restar:
  1. 5 6 a 2 de 3 8 a 2 – 5 6 a 3 8 a 2 – 5 6 a– 5 6 a 2 = 3 8 a 2 – 5 6 a 2 – 5 6 a = 9 a 2 –20 a 2 24 – 5 6 a = – 11 a 2 24 – 5 6 a
  2. 1 2 a– 3 5 bde8a+6b–5 8a+6b–5 – 1 2 a+ 3 5 b ¯ (8a– 1 2 a ) +(6b+ 3 5 b ) –5 = 16a–a 2 + 30b+3b 5 –5 = 15a 2 + 33b 5 –5
  3. 7 9 x 2 yde x 3 + 2 3 x 2 y–6 x 3 + 2 3 x 2 y–6– 7 9 x 2 y = x 3 +( 2 3 x 2 y– 7 9 x 2 y ) –6 = x 3 + 6 x 2 y–7 x 2 y 9 –6 = x 3 – x 2 y 9 –6
  4. 1 2 a– 3 4 b+ 2 3 cdea+b–c a+b–c – 1 2 a+ 3 4 b– 2 3 c ¯ (a– 1 2 a ) +(b+ 3 4 b ) +(–c– 2 3 c ) = 2a–a 2 + 4b+3b 4 + –3c–2c 3 = a 2 + 7b 4 – 5c 3
