Hello,

My 9th grader was given this problem:
FIND

(A / B) . (C / D)
where
A = Y squared + 3 . Y cubed
B = Y squared + 4
C = 2 . Y + Y squared
D = Y + 4 Y squared + 3 Y cubed

His teacher gave the answer as (Y - 7) . (Y - 2)

Please help as we don't know how to get to the teacher's answer and even don't know if the answer is correct !

Thank you

If I am reading this properly the problem is to find  ^A/_B. ^C/_D where

• A = Y² + 3 Y³
  
  
• B = Y² + 4
  
  
• C = 2 Y + Y²
  
  
• D = Y + 4 Y² + 3 Y³

My feeling is that there is an error in the statement of the problem as you sent it to me, or as I interpreted it.
