EXPRESIONES ALGEBRÁICAS FRACCIONARIAS

RESTRINGIR
1. a/1 , 1/a
  1. SE INDETERMINA
    1. 1/a , a=0
  2. SE ANULA
    1. a/1 , a=0
  3. EJEMPLO
    1. (3x+1)/(2+4x)
      1. 2+4x=0 4x= -2 x=(-2)/4 x=(-1)/2 se indetermina
      2. 3x+1=0 3x= -1 x= (-1)/3 se anula
SIMPLIFICACIÓN DE EAF
1. (〖2a〗^2+2)/4a=(2(a^2+1))/4a= (a^(2 )+1)/2a
EAF
DIVISIÓN DE EAF
1. 2axy/3a ∶ 2x/3y 2xy/3a x 3y/2x y^2
ADICIÓN
1. CON IGUAL DEMINADOR
  1. (3a-1)/5+ (2a-7 )/5-2/5= (3a-1+2a-7-2)/5= (3a+2a-1-7-2)/5= (5a-10)/5= (5(a-2) )/5= a-2
2. CON DIFERENTE DENOMINADOR
  1. 6/x^2 + 7/2x-5/3x= (6*6+3x*7-2x*5)/(6x^2 )= (36+21x-10x)/〖6x〗^2 = (36+11x)/〖6x〗^2
SUSTRACCIÓN
1. CON IGUAL DENOMINADOR
  1. (m-2)/(2m )- (3m-1)/2m = (m-2-3m+1)/2m= (-2m-1)/2m
2. CON DIFERENTE DENOMINADOR
  1. m-2- 5/(m+1)= ((m+1)(m-2)-5)/(m+1)= (m^(2 )-2m+m-2-5)/(m+1)= (m^2-m-7 )/(m+1)
