Use the FOIL Method to find (9 - r) (2 - 3r)

(9 - r) (2 - 3r) =

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)
