anonymous · Answer

Part A: Add x^2 + 1 and 3x - 2 together and simplify.
Part B: Subtract 3x - 2 from x^2 + 1 and simplify 
Part C: Multiply ..........
You get the procedure now probably

anonymous · Answer

You won't be able to simplify d and e so don't stress too much on those.

anonymous · Answer

already have answer in A & B but for C,D,& E still dont have

anonymous · Answer

Part C : fg(x) = (x^ + 1)(3x - 2) =  now just FOIL that out.

anonymous · Answer

please help how to solve C,D, & E

anonymous · Answer

C. f.g= (x^2+1).(3x-2)
       i use FOIL to get this
      (x*3x)+(x*-2)+(1*3x)+(1*-2)
       3x^2+(-2x)+3x+(-2)
   f.g= 3x^2+x-2
