Subtract:
|dw:1393392757815:dw|
Get common denominators.
this might sound dumb but... how exactly do I do that??
Apply the basic fraction rules you learned.
Yeah that's what I am confused about..... Can you explain how?
Here use this formula :) \[\large \frac{ a }{ b } + \frac{ c }{ d } = \frac{ ad + bc }{ bd }\]
^Yea, pretty much that
\[\frac{ 5 }{ x-2 } + \frac{ 3 }{ x+2 } = \frac{ 5(x+2) + 3(x-2) }{ (x-2)(x+2) }\]
8x+4/ (x-2)(x+2) ??
Think of it this way, say we have: \[\LARGE \frac{1}{3}+\frac{2}{5}\] How could we add them? Get common denominators: \[\LARGE \frac{1}{3}*\frac{5}{5}+\frac{2}{5}*\frac{3}{3}\] Now we can add them: \[\LARGE \frac{5}{15}+\frac{6}{15}\] Same with yours,,
Thank you @AshleyAlley<3 T_T
Okay so was my answer correct? I get it now
Yea, it's right.
Oh, wait your original question was to subtract them not add, ahhhh my bad >.<
\[\frac{ 5 }{ x-2 } - \frac{ 3 }{ x+2 } = \frac{ 5(x+2)- 3(x-2) }{ (x-2)(x+2) }\]
you're welcome @Luigi0210 xD
