You can put this solution on YOUR website!

When you are making perfect squares,
\r
\n" ); document.write( "\n" ); document.write( "the easy way is just to take HALF of the value of the middle term,
\r
\n" ); document.write( "\n" ); document.write( "and then square it.
\r
\n" ); document.write( "\n" ); document.write( "Half of -12 is -6.
\r
\n" ); document.write( "\n" ); document.write( "-6 squared is 36.
\r
\n" ); document.write( "\n" ); document.write( "The expression should then be:
\r
\n" ); document.write( "\n" ); document.write( "\"u%5E2-12u%2B36\"
\r
\n" ); document.write( "\n" ); document.write( "And if we continue, then we can see that this can be factored as:
\r
\n" ); document.write( "\n" ); document.write( "\"%28u-6%29%28u-6%29\"
\r
\n" ); document.write( "\n" ); document.write( "or even more simply written as \"%28u-6%29%5E2\"
\r
\n" ); document.write( "\n" ); document.write( "which is WHY we do this. :)
\r
\n" ); document.write( "\n" ); document.write( "Of course, this only works when the coefficient for the \"x%5E2\" term is 1, so be careful when trying this with trickier expressions.
\r
\n" ); document.write( "\n" ); document.write( "There's a LOT more to it, but this is the basic info you need to answer the question.
\r
\n" ); document.write( "\n" ); document.write( "I hope this helps! :)
\r
\n" ); document.write( "\n" ); document.write( "Email Scott: neatmath@yahoo.com for help with specific problems,
\r
\n" ); document.write( "\n" ); document.write( "or to inquire about mathematics tutoring via email or other methods.
\r
\n" ); document.write( "\n" ); document.write( "Paypal is always accepted for single problems or for more intensive tutoring!
\r
\n" ); document.write( "\n" ); document.write( "Single problems would range from 50 cents to 5 dollars each, depending on the complexity.
