Your expression might be properly written as ...
3y/(y^2 +7y +10) +2/(y+2)
As you have written it, it simplifies to ...
3(y/y)2 +7y +10 +2/y +2 = 3·2 +7y +2/y +12
= 7y +2/y +18
Please note, too, the exponentiation symbol (^).

You multiply polynomials by multiplying each part of one polynomial by all the other parts of the others, and then adding it all. For example: (ax+b) * (x+c) = (ax*x)+(ax*c)+(b*x)+(b*c) =
