The distributive property basically means that you are going to multiply everything on the outside of the parenthesis bit everything on the inside of the parenthesis.

For example: in 2(4+x), you need to multiply 2 by 4 and 2 by x to get 8+2x

This is true also for variables: in x(3-2x), you need to multiply x by 3 and x by 2x to get 3x-2x^2

And for other equations: in (2+x)(3+x), you need to use FOIL (Front, Outside, Inside, Last). Multiply the following -->Front: 2*3, Outside: 2*x, Inside: x*3, and Last: x*x, combine like terms, and you end up with x^2+5x+6
