You can put this solution on YOUR website!
These just expressions, not equations, that you can solve (no equal sign)
\n" ); document.write( ":
\n" ); document.write( "-2(3x^2 + x + 1) +6(-3x^2 -2x -2)
\n" ); document.write( "multiply what's inside the bracket, remove the brackets
\n" ); document.write( "-6x^2 - 2x - 2 -18x^2 - 12x - 12
\n" ); document.write( "combine like terms
\n" ); document.write( "-6x^2 - 18x^2 - 2x - 12x - 2 - 12
\n" ); document.write( "-24x^2 - 14x - 14
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "(3y^3 - 4y +2) + (2y+1) - (y^3 - y^2 +4)
\n" ); document.write( "remove the brackets, no change if positive, if negative change the signs
\n" ); document.write( "3y^3 - 4y + 2 + 2y + 1 - y^3 + y^2 - 4
\n" ); document.write( "Combine like terms
\n" ); document.write( "3y^3 - y^3 + y^2 - 4y + 2y + 2 + 1 - 4
\n" ); document.write( "2y^3 + y^2 - 2y - 1 \n" ); document.write( "
\n" );
