You can put this solution on YOUR website!
\"+10x%5E2+=+20x+%2B+30+\"
\n" ); document.write( "Subtract \"20x\" from both sides
\n" ); document.write( "\"+10x%5E2+-+20x+=+30+\"
\n" ); document.write( "Divide both sides by \"10\"
\n" ); document.write( "\"+x%5E2+-+2x+=+3+\"
\n" ); document.write( "Now you can complete the square.
\n" ); document.write( "Take 1/2 of the coefficient of \"x\",
\n" ); document.write( "square it, and add it to both sides
\n" ); document.write( "\"+x%5E2+-+2x+%2B+%28-2%2F2%29%5E2+=+%28-2%2F2%29%5E2+%2B+3+\"
\n" ); document.write( "\"+x%5E2+-+2x+%2B+1+=+1+%2B+3+\"
\n" ); document.write( "Both sides are now a perfect square
\n" ); document.write( "\"+%28+x+-+1+%29%5E2+=+2%5E2+\"
\n" ); document.write( "Take the square root of both sides
\n" ); document.write( "\"+x+-+1+=+2+\" ( this is the (+) square root)
\n" ); document.write( "\"+x+=+3+\"
\n" ); document.write( "and
\n" ); document.write( "\"+x+-+1+=+-2+\" (this is the (-) square root)
\n" ); document.write( "\"+x+=+-1+\"
\n" ); document.write( "The solutions are \"x=3\" and \"x=-1\"
\n" ); document.write( "
\n" );
