(9/x^2)+2=(-9/x)

jhonyy9 (jhonyy9):

common denominator you know what will be ?

jhonyy9 (jhonyy9):

so if x^2 than what you need to do with 2 and -9/x ?

jhonyy9 (jhonyy9):

ahhh ok the first step will be add to both sides 9/x

jhonyy9 (jhonyy9):

what you will get hence ?

jhonyy9 (jhonyy9):

come on courage please

OpenStudy (anonymous):

sorry holon i got -11/9

OpenStudy (anonymous):

i know you need t lcd but thats where i ke messing up

jhonyy9 (jhonyy9):

how please step by step ?

OpenStudy (anonymous):

i got lcd x(x^2) so times each side by that

jhonyy9 (jhonyy9):

why ? this not is right

jhonyy9 (jhonyy9):

lcd is x^2

OpenStudy (anonymous):

ok so then do you times both sides by x^2

jhonyy9 (jhonyy9):

why ?

jhonyy9 (jhonyy9):

9/x^2 +2=-9/x 9/x^2 +9/x +2=0 the lcd is x^2 than 9 +9x +2x^2 =0 --- so right ?

OpenStudy (anonymous):

but then what do you do

jhonyy9 (jhonyy9):

and now you solve this for x - so but befor all you need to make the restrictions for x because there are fractions and you need to push the recstriction for x when for what value of x the fractions will be undefined ?

OpenStudy (anonymous):

i dont understand what that means
