Preform operations and simplify:
\n" ); document.write( " $\"%281%29%2F%28x-y%29\"$ - $\"%282x%29%2F%28x%5E2-y%5E2%29\"$ + $\"%281%29%2F%28x%2By%29\"$
\n" ); document.write( "Factor the dif of squares
\n" ); document.write( " $\"%281%29%2F%28x-y%29\"$ - $\"%282x%29%2F%28%28x%2By%29%28x-y%29%29\"$ + $\"%281%29%2F%28x%2By%29\"$
\n" ); document.write( ":
\n" ); document.write( "The common denominator is (x+y)(x-y), therefore we have
\n" ); document.write( " $\"%28%28x%2By%29-2x%2B%28x-y%29%29%2F%28%28x%2By%29%28x-y%29%29\"$ = $\"%28x%2By-2x%2Bx-y%29%2F%28%28x%2By%29%28x-y%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "Combine like terms in the numerator
\n" ); document.write( " $\"%28x+-+2x+%2B+x+%2B+y+-+y%29%2F%28%28x%2By%29%28x-y%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "which is
\n" ); document.write( " $\"0%2F%28%28x%2By%29%28x-y%29%29\"$ = 0 \n" ); document.write( "
