So the key to solving these problems is by multiplying things term by term. First let's start with 4 and 3b+2 4*3b= 12b and 4*2 =8 so you get 12b+8 then we multiply this by 4b-3 12b*4b=48b^2, 12b*-3= -36b, 8*4b=32b, and 8*-3= -24. So you get 48b^2-36b+32b-24. Then you combine like terms, so you get 48b^2-4b-24 as your final answer.
