You can put this solution on YOUR website!
$\"x%5E2%2B2x=3\"$
\n" ); document.write( "'
\n" ); document.write( "Steps:
\n" ); document.write( " $\"x%5E2%2B2x-3=3-3\"$
\n" ); document.write( " $\"x%5E2%2B2x-3=0\"$
\n" ); document.write( "The part of the left side expression, $\"x%5E2%2B2x\"$ , is like a rectangle of sides x and x+2. The missing square piece, when part of the rectangle is rearranged visually would be $\"%282%2F2%29%5E2=1\"$ .
\n" ); document.write( "THAT is what you add to both sides of the general form equation to Complete the Square.
\n" ); document.write( " $\"x%5E2%2B2x%2B1+-3+=+0%2B1\"$
\n" ); document.write( " $\"%28x%2B1%29%5E2-3=1\"$
\n" ); document.write( " $\"%28x%2B1%29%5E2=1%2B3\"$
\n" ); document.write( " $\"%28x%2B1%29%5E2=4\"$
\n" ); document.write( " $\"x%2B1=0%2B-+2\"$ ----the zero is included here only so the site rendering works. It is not needed when done on paper.
\n" ); document.write( " $\"x=-1%2B2\"$ or $\"x=-1-2\"$
\n" ); document.write( " $\"highlight%28x=1%29\"$ or $\"highlight%28x=-3%29\"$ \n" ); document.write( "

\n" );
