ok i have no idea how to solve this problem. i tried to fix x to some arbitrary value and just could not get this problem to work out...

the problem says that c and d are constants and it wants me to find the value of the product??? any help on this problem would be appreciated....

i even tried to factor out the right side and add the negative of the right side to see if i could get something going, but i am really stuck....

thanks in advance!
