If f(X) = 25 -x ^2 and g(x) = x+5, what is (f/g) (x)?

Question

anonymous · Answer

help please i dont understand

jhonyy9 · Answer

so f/g (x) what mean ? f(x) divide by g(x)

yes ?

anonymous · Answer

I dont understand?

jhonyy9 · Answer

so f(x) = 25-x^2 

then you know formula a^2 -b^2 =(a-b)(a+b) so you can using it here because you can rewriting f(x) = (5-x)(x+5)

ok ?

jhonyy9 · Answer

and now than you rewrite f/g(x) how will be ?so using this factored form of f(x)

anonymous · Answer

5x+25-x^2-5x??

anonymous · Answer

yeah i still dont get what the answer is ??

jhonyy9 · Answer

so will be 

(5-x)(5+x)
---------- = ?
  x+5

jhonyy9 · Answer

now this is easy just simplifie what you can 

ok ?

anonymous · Answer

x+5??
is that the answer

jhonyy9 · Answer

why x+5 ? when there is down and up too ?

this will be simplified so then what will remained there ?

anonymous · Answer

i give up

jhonyy9 · Answer

(5-x)(5+x)
---------- than simplifie 5+x by 5+x what will get ?
   5+x

jhonyy9 · Answer

5+x from numerator will be simplified by 5+x from denominator so than will get 5-x

yes ?

jhonyy9 · Answer

hope you understand it now 

good luck

bye
