Question

Calcula:
a) 1/x-6 + 3x/2

b) 5/x2+x-6 + 2x/x2+2x-3

c) 2x+2/x3-2x2-9x+18 - x-3/x3-x2-14x+24

Answer 1

B.  5/x²+x-6 + 2x/x²+2x-3
     5/(x₊3)(x-2)₊2x/(x₊3)(x-1)
      5(x₊3)(x-1)₊2x(x₊3)(x-2) / (x₊3)(x-2)(x₊3)(x-1)
      RPTA : 5₊2X
      
a. 1/x-6₊3x/2
     2₊3x(x-6)/2(x-6)
      2₊3x/2

Rpta: 2₊3x/2
