Question

find the product of -4(v+1)

Answer 1

-4v-4

Answer 2

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

Answer 3

then how do you get the other -4? that NK309

Answer 4

got

Answer 5

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

Answer 6

mmm, what? lol

Answer 7

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

Answer 8

i dont know how. :o

Answer 9

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)

Answer 10

so like.. v+1=1v then x-4? or am i totally wrong?

Answer 11

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?

Answer 12

kindaaa. but i dont get how they get -4x-4

Answer 13

i got -4x+-8

Answer 14

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

Answer 15

you could get -4x+-4

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

Answer 16

lol.. what the hell am i doing. :/

Answer 17

you were so close that time.... i reckon you'll have it ont he next problem

Answer 18

maybe, lol.

Answer 19
