    multiply -4 times V then multiply it by 1. which is -4V + 1

    no its the distributive property. a (b+c) =ab + ac

    if you ever have a problem like that, # (#+#), use the distributive prop

    to 'use the distributive property' is the same as 'multiply it out, or expand the brackets' so #1(#2 + #3) = (#1 times #2) plus (#1 times #3)

    wrong, but you seem to be getting closer :) v+1 is different to 1v because 1v is one multiplied by v just like v+4 is different to 4v because instead of having 4 + v (or 4 + 1v) its 4 multiplied by v does that make sense?

    its because of the minus sign out the left side of the 4 -4 (v+1) ^ the one above this: ^ that minus sign makes it negative 4 multiplied by each thing in the bracket, so you have to change the sign every time

    you could get -4x+-4 but if you got -4x+-8 then you would have had -4(x+2)
