Answer 1

a + b + ab + a²     (a + b) + a(b + a)        (a + b)(1 + a)

------------------- = -------------------------- = ------------------- = 1 + a

      a + b                       a + b                        (a  +b)

 

 

2a + b + ab + 2      2a + 2 + ab + b          2(a  +1) + b(a + 1)     (a + 1)(2 + b)

-------------------- = ------------------------- = -------------------------- = ------------------ = 2 + b

       a + 1                       a + 1                            a + 1                          (a  +1)
