You can put this solution on YOUR website!
Y^3(10X^2+3Y-1)(5X^3-3XY-Y) FIRST WE MULTIPLY BOTH TERMS ( )( ) BY Y^3 THUS
\n" ); document.write( "(10X^2Y^3+3Y^4-Y^3)(5X^3Y^3-3XY^4-Y^4) NOW MULTIPLY THESE TWO TERMS THUS
\n" ); document.write( "(5X^3Y^3-3XY^4-Y^4)
\n" ); document.write( "---------------------------------------
