1st problem
\n" ); document.write( ".
\n" ); document.write( "Exactly correct , congrats
\n" ); document.write( "now @x=-2, we have a \"hole\" due to cancelling (x+2)
\n" ); document.write( "and at x=3, we have an asymptote ,,,,due to (x-3) in denominator
\n" ); document.write( "zero at x=2, due to (x-2) in num
\n" ); document.write( ".
\n" ); document.write( "2 nd problem
\n" ); document.write( ".
\n" ); document.write( "4 (x+3) / { (x-1) (x+2) } + { (x+3) (x-2) } / (x-1)
\n" ); document.write( ".
\n" ); document.write( "Use LCD of (x-1) (x+2)
\n" ); document.write( ".
\n" ); document.write( "[ 4 (x+3) + { (x+3)(x-2)(x+2) } ] / [ (x-1) (x+2) ]
\n" ); document.write( ".
\n" ); document.write( "[ (x+3) { 4 + (x-2)(x+2) } ] / (x-1)(x+2)
\n" ); document.write( ".
\n" ); document.write( "[ (x+3) { 4 + x^2 -4} ] / (x-1)(x+2)
\n" ); document.write( ".
\n" ); document.write( "{ (x+3) x^2 }/ (x-1)(x+2)
\n" ); document.write( ".
\n" ); document.write( "(x^3 +3x^2 ) / (x-1)(x+2)
\n" ); document.write( ".
\n" ); document.write( "Asymptotes at x=1, x=-2,,,,,,due to (x-1)(x+2) in den
\n" ); document.write( "zero's at x=0,,x=-3,, due to factors in num
