You can put this solution on YOUR website!
You are doing fine so far.\r
\n" ); document.write( "\n" ); document.write( "\"2x%5E2+%2B+6x+%2B+9+=+225\" Subtract 225 from both sides.
\n" ); document.write( "\"2x%5E2+%2B+6x+-+216+=+0\" Factor a 2 just to make process a little easier.
\n" ); document.write( "\"2%28x%5E2+%2B+3x+-+108%29+=+0\" Factor the parentheses.
\n" ); document.write( "\"2%28x+-+9%29%28x+%2B+12%29+=+0\" Apply the zero products principle.
\n" ); document.write( "\"%28x+-+9%29+=+0\" or \"x+%2B+12+=+0\"
\n" ); document.write( "If x - 9 = 0, then x = 9
\n" ); document.write( "If x + 12 = 0, then x = -12 Discard this solution as the length can't be negative.\r
\n" ); document.write( "\n" ); document.write( "The lengths of the sides are:
\n" ); document.write( "9 cm and 12 cm.\r
\n" ); document.write( "\n" ); document.write( "Check:\r
\n" ); document.write( "\n" ); document.write( "\"15%5E2+=+9%5E2+%2B+%289%2B3%29%5E2\"
\n" ); document.write( "\"225+=+81+%2B+144\"
\n" ); document.write( "\"225+=+225\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
