subtract, write answer in lowest terms:
\n" ); document.write( "in words it would be 9x over x2-49 minus 5 over 7-x
\n" ); document.write( ":
\n" ); document.write( " $\"%289x%29%2F%28%28x%5E2-49%29%29\"$ - $\"5%2F%28%287-x%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "Note that (x^2-49) is the \"difference of squares, factor:
\n" ); document.write( "Change the signs in (7-x) multiply by -1
\n" ); document.write( " $\"%289x%29%2F%28%28x-7%29%28x%2B7%29%29\"$ - $\"5%2F%28-1%28x-7%29%29\"$
\n" ); document.write( "Which is:
\n" ); document.write( " $\"%289x%29%2F%28%28x-7%29%28x%2B7%29%29\"$ + $\"5%2F%28%28x-7%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "The common denominator
\n" ); document.write( " $\"%289x+%2B+5%28x%2B7%29%29%2F%28%28x%2B7%29%28x-7%29%29%29\"$ = $\"%28%289x+%2B+5x+%2B+35%29%29%2F%28%28x%2B7%29%28x-7%29%29%29\"$ = $\"%2814x+%2B+35%29%2F%28%28x%2B7%29%28x-7%29%29%29\"$ = $\"%287%282x+%2B+5%29%29%2F%28%28x%2B7%29%28x-7%29%29%29\"$ \n" ); document.write( "
