multiply -4 times V then multiply it by 1. which is -4V + 1
then how do you get the other -4? that NK309
no its the distributive property. a (b+c) =ab + ac
mmm, what? lol
if you ever have a problem like that, # (#+#), use the distributive prop
i dont know how. :o
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)
so like.. v+1=1v then x-4? or am i totally wrong?
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?
kindaaa. but i dont get how they get -4x-4
i got -4x+-8
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)
lol.. what the hell am i doing. :/
you were so close that time.... i reckon you'll have it ont he next problem
you can do it!
