You can put this solution on YOUR website!
You are given the expression:
\n" ); document.write( " $\"7x%5E2%2B24x%2B%2813%2F25%29x%5E2-16-2x%5E2-%283%2F25%29x%5E2-16\"$ .
\n" ); document.write( "To solve it, you first collect the like terms:
\n" ); document.write( " $\"7x%5E2-2x%5E2%2B%2813%2F25%29x%5E2-%283%2F25%29x%5E2%2B24x-16-16\"$
\n" ); document.write( " $\"5x%5E2%2B%2810%2F25%29x%5E2%2B24x-32\"$
\n" ); document.write( " $\"5x%5E2%2B.6x%5E2%2B24x-32\"$
\n" ); document.write( "Multiply by 10 to remove the decimal place that was created by calculating 10/25 = .6.
\n" ); document.write( " $\"50x%5E2%2B6x%5E2%2B240x-320\"$
\n" ); document.write( " $\"56x%5E2%2B240x-320\"$
\n" ); document.write( "Now divide by 8 to simplify:
\n" ); document.write( " $\"7x%5E2%2B30x-40\"$
\n" ); document.write( "At this point, you can stop, unless you were told to factor it or use the quadratic equation. \n" ); document.write( "

\n" );
