1.1. Recall that a polynomial 3:2 y2 in two variables at: and y factors into a product 3:2 3/2 = (a: y)(m + y). Therefore, the ratio m'ZE = 3: + y can be evaluated at $ 3: = y = c for an arbitrary real number c, and the result is 3:2y2 m y m=y=c = (33+y)|m=y=c = c+c= 20. Here, we cannot evaluate a: = y = c before we calculate the fraction if? rst. The evaluation takes place only after the fraction is calculated by cancelling the common factor (a: y). 1.1.1. Problem. Following the above example, evaluate the following, giving all de- tails. 3 3 5631 m y m=y=c
