$\"+c%5E2+-+4+=+0+\"$
\n" ); document.write( "This is the difference of two squares. Get used to seeing this ... A LOT!!
\n" ); document.write( "Memorize this form:
\n" ); document.write( " $\"+%28x%2By%29%28x-y%29=x%5E2+-+y%5E2+\"$
\n" ); document.write( "In this case ... the c is the x value and the 4 is the y value.
\n" ); document.write( " $\"+%28c-2%29%28c%2B2%29=0+\"$
\n" ); document.write( "set each piece equal to 0
\n" ); document.write( " $\"+c-2+=+0+\"$ and $\"+c%2B2=0+\"$
\n" ); document.write( " $\"+c=2+\"$ and $\"+c+=+-2+\"$
\n" ); document.write( " \n" ); document.write( "
