Your answer, - 3 is CORRECT!! Good work!
\n" ); document.write( "
\n" ); document.write( " ------------- Factoring denominators that can be factored
\n" ); document.write( " ------------- Factoring denominator on right, further
\n" ); document.write( "We now see, based on the most previous equation that \"matrix%283%2C1%2C+a+%3C%3E0%2C+a+%3C%3E+-+5%2C+a+%3C%3E+-+2%29\"
\n" ); document.write( "Since the answer that you got - which is correct - is NONE of the above restricted values for \"a\", then we can say that it is indeed the solution.
\n" ); document.write( "The only thing I see here that's wrong is your calculation of \"%28a+%2B+3%29%5E2\".
\n" ); document.write( "It's not part of any of the DENOMINATORS, so that's not how you check to see if your answer is CORRECT! \n" ); document.write( "
\n" );
