Will someone please explain this math problem to me? -2c(2/c squared+c squared)?

I don't have to know what C is, it just has to be simplified w/ no parenthesis

Will someone please explain this math problem to me? -2c(2/c squared+c squared)?
yea all you have to do is use the the distributive property


a(a+b) = aa+ab





so





-2c(2/c^2 + c^2) = -2c/c^2 + 2c^3 it simplifies to -2^2 - 2c^3 or 4 - 2c^3
Reply:You have to distribute.





-4c/c^2 - 2c^3 The c's can be canceled in the fraction.


-4/c - 2c^3
Reply:I got something a little different . . .





. . . . . . . 2


-2c ( --------------- )


. . . . c^2 + c^2








. . . . . . 2


-2c ( ----------- ) , Cancel out the two's . . .


. . . . . 2c^2











. . . . . .1


-2c ( -------- ), now multiply the -2c . . .


. . . . c^2








-2c . . . . 1 . . . . . -2c


------ x ---- =. . . . -------


1. . . . . c^2. . . . . c^2
Reply:-2c (2/c squared + c squared)





-2c ( 4/ c^2 + c^2 ) multiply





-2c * 4/c^2 + -2c * c^2





-8/c -2 c^3





(-2c^4 - 8)/ c
