Add or subtract as indicated.
\[\frac{ 5 }{ x-2 }-\frac{ 3 }{ x-2 }\]
@hartnn
the denominator is common! you can directly combine the numerator :)
\(\large \dfrac{☺}{♥}+\dfrac{☻}{♥}=\dfrac{☺+☻}{♥ }\)
this is correct right because when we subtract 3 from 5 we get 2 but the denominator has a positive and negative
so the actual question is this ? \(\large \frac{ 5 }{ x+2 }-\frac{ 3 }{ x-2 }\) or something else ?
no the question is
so that just equals \(\dfrac{2}{x-2}\) there will be no x+2
here are the choices they gave me and i got wrong
then the question must have a (x+2) in it
if there is a positive the second choice is right
\(\dfrac{5}{x+2}-\dfrac{3}{x-2} = \dfrac{2x-16}{(x+2)(x-2)}\) \(\dfrac{5}{x-2}-\dfrac{3}{x+2} = \dfrac{2x+16}{(x+2)(x-2)}\)
from were did u get -16
for this question there is no correct answer i guess
\(5(x-2)-3(x+2) = 5x-10 -3x-6 = 2x -16\) the question itself is incorrect(not clear) :P
i will message my teacher to make it clear....
yes.
