pooja195
  • pooja195
We need to use the distributive property
anonymous
  • anonymous
That picture just confused me even more
pooja195
  • pooja195
Its just an example
anonymous
  • anonymous
where did another blue come from
pooja195
  • pooja195
When you distribute the basically multiply the number outside of the parentheses by the numbers inside of the parentheses understood or confused?
anonymous
  • anonymous
Sort of understood, can you give me an easy example please

Ok so you move the x to the 5 and multiply
anonymous

Can you give me an easy one so I can solve it myself

2m. 8?
pooja195
  • pooja195
Almost correct! :D its 2m-8+1 Now combine like terms :)
anonymous
  • anonymous
Why would it be +1 it says -1 there
pooja195
  • pooja195
-8 + 1 =?
anonymous
  • anonymous
-7?
pooja195
  • pooja195
yes so we have 2m-7 <---final answer
anonymous
  • anonymous
Ok
anonymous
  • anonymous
Im gonna do the first one again
anonymous
  • anonymous
2(m − 4) + 1?
anonymous
  • anonymous
So first we bring the m to the 2 so 2mx4+1
anonymous
  • anonymous
but how do we do the second part, − 4) + 1
anonymous
  • anonymous
@pooja195
pooja195
  • pooja195
Not quite we need to MULTIPLY
anonymous
  • anonymous
− 4) + 1 but how will we multiply
pooja195

|dw:1439222259894:dw|
anonymous
  • anonymous
im stumpted on inequalities and these expressions
pooja195
  • pooja195
Try again dont give up! :)
anonymous
  • anonymous
4 x 2 = 8
pooja195
  • pooja195
*-4
anonymous
  • anonymous
Oh then -4 x 1
pooja195
  • pooja195
Where are you getting the 1 from?
anonymous
  • anonymous
-1
anonymous
  • anonymous
in the end of the expression
pooja195
  • pooja195
ignore that for right now
anonymous
  • anonymous
Ok so what do I multiply then
pooja195
  • pooja195
Distribute: =(2)(m)+(2)(−4)+1 =2m+−8+1 Combine Like Terms: =2m+−8+1 =(2m)+(−8+1) =2m+−7
anonymous
  • anonymous
man all those symbols and numbers
anonymous
  • anonymous
im so bad at this
anonymous
  • anonymous
im gonna fail flvs
anonymous
  • anonymous
it just doesnt make sense to me no matter how much I try to understand
pooja195
  • pooja195
no you wont! im not gonna let u! ok Distribute \[\huge~\rm~(2)(m)+(2)(−4)\] Do you understand this?
anonymous
  • anonymous
i understand 2m because we bring the m to the 2 (is that distributing)
anonymous
  • anonymous
and the +
pooja195
  • pooja195
Good -4 comes from the minus sign
pooja195
  • pooja195
therefore it is a negative 4
anonymous
  • anonymous
yes so what do we do with the -4
pooja195
  • pooja195
ok Distribute \[\huge~\rm~(2)(m)+(2)(−4)\]
pooja195
  • pooja195
Now multiply ignore the plus sign for right now
anonymous
  • anonymous
2 x 2 = 4
pooja195
  • pooja195
where in the world did u get 2 x 2 from?
anonymous
  • anonymous
umm you said get rid of the +
anonymous
  • anonymous
then its 2m + 2
pooja195
  • pooja195
2 x m= ? 2 x -4 =?
anonymous
  • anonymous
yeah but we dont know what 2xm is
pooja195
  • pooja195
correct it remains 2m
anonymous
  • anonymous
yes so 2m x 2
pooja195
  • pooja195
No 2m -8 2 times -4 = -8
