you want to multiply the first numbers in the parenthesis. that gives you 2x^2 
then you multiply the outside number in the parenthesis 2*4=8
then multiply the inside numbers 3*x=3x
then multiply the last numbers 3*4=12
that gives you 2x^2+3x+20

Do the same thing with the answers they give you to find the correct answer
