(5.9x^3+3.4x^2-7)-(2.9x^3-9.6x^2+3)
\n" ); document.write( "=(45x^3 +12x^2 -7) -(18x^3-54x^2+3)
\n" ); document.write( "remove the paranthesis
\n" ); document.write( "=45x^3+12x^2 -7 -18x^3 +54x^2 -3
\n" ); document.write( "take the like terms together and simplify\r
\n" ); document.write( "\n" ); document.write( "45x^3-18x^3 +12x^2+54x^2 -7-3
\n" ); document.write( " => (45-18)x^3 + (12+54)x^2 -(7+3)
\n" ); document.write( " => 27x^3 + 66x^2 -10
\n" ); document.write( "
\n" );
