$\"%287x%5E3-6x%5E2%2B6%29+-+%282x%5E2+-4x-9%29+\"$ \r

\n" ); document.write( "\n" ); document.write( " $\"7x%5E3-6x%5E2%2B6+-+2x%5E2+%2B+4x+%2B+9+\"$ Distribute (to ALL terms)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"7x%5E3-8x%5E2%2B4x%2B15+\"$ Combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So $\"%287x%5E3-6x%5E2%2B6%29+-+%282x%5E2+-4x-9%29+\"$ fully simplifies to $\"7x%5E3-8x%5E2%2B4x%2B15+\"$ \r

\n" ); document.write( "\n" ); document.write( "In other words $\"%287x%5E3-6x%5E2%2B6%29+-+%282x%5E2+-4x-9%29+=7x%5E3-8x%5E2%2B4x%2B15+\"$ for all values of x.\r
