Consider the division of 8y2 – 12y + 4 by 4y.

what is the value of a and b?
a = 2y and b = 3
a = and b = –3y
a = 2y and b = –3
a = and b = 3y

8y^2 -12y +4 / 4y = 2y -3     so from this result that a=2y and b= - 3
8y^2

   0   -12y
        -12y
     
           0    4

hope i ve understood it right what wan being a and b because you dont wrote there in the text of this exercise 

so than the 3rd  choice is right
