(4x^6-8x^4+9x^3-12x^2+15)-(2x^6+7x^5-13x^4-4x^3+12x-10)
\n" ); document.write( "I need to simplify this
\n" ); document.write( "-----------------
\n" ); document.write( "Combine like terms.
\n" ); document.write( "Like terms are those with the same exponent.
\n" ); document.write( "4x^6 - 2x^2 = 2x^6
\n" ); document.write( "
\n" ); document.write( "
\n" );
