\n" ); document.write( "Let n=the positive number
\n" ); document.write( "and then from my let statement and the word problem given, i took a guess and did this:

You can put this solution on YOUR website!
What you have done so far is absolutely correct!
\n" ); document.write( " $\"n%5E2+=+5n%2B6\"$ You should be able to recognise this as a quadratic equation (the variable n is squared) so let's get into the standard form for quadratic equations.
\n" ); document.write( " $\"n%5E2-5n-6+=+0\"$ This factorable so...
\n" ); document.write( " $\"%28n%2B1%29%28n-6%29+=+0\"$ Apply the zero product rule.
\n" ); document.write( " $\"n%2B1+=+0\"$ or $\"n-6+=+0\"$ which means that...
\n" ); document.write( " $\"n+=+-1\"$ or $\"n+=+6\"$
\n" ); document.write( "Now since the problem specifies that \"The square of a positive number is...\"
\n" ); document.write( "you can discard the negative solution (n = -1) and your answer is n = 6. \n" ); document.write( "

\n" );
