\n" ); document.write( "\n" ); document.write( "Looking at it, i think you meant to type the following:\r
\n" ); document.write( "\n" ); document.write( " $\"+1%2F%28r%5E2-1%29+=+2%2F%28r%5E2%2Br-2%29+\"$
\n" ); document.write( " $\"+1%2F%28%28r%2B1%29%28r-1%29%29+=+2%2F%28%28r-1%29%28r%2B2%29%29+\"$
\n" ); document.write( " $\"+1%2F%28r%2B1%29+=+2%2F%28r%2B2%29+\"$
\n" ); document.write( "(r+2) = 2(r+1)
\n" ); document.write( "r+2 = 2r+2
\n" ); document.write( "2 = r+2
\n" ); document.write( "0 = r\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, answer is r=0\r
