    Step 1: multiply 9 and 2 which gets you 18

    step 2: multiply 9 and - 3r which gets you - 27r

    step 3: multiply - r and 2 which gets you - 2

    step 4: multiply - r and - 3r which gets you 3r

    now you should have: 18-27x-2x+3x^2

    collect like terms and it should now look like:

    3x^2-29x+18 (< - answer)
