x^3+4x^2+x-6=0
\n" ); document.write( "with synthetic division, using -3
\n" ); document.write( "1-----4----1---- -6
\n" ); document.write( "1-----1--- -2-----0
\n" ); document.write( "(x+3)(x^2+x-2)=0, so -3 is a root
\n" ); document.write( "(x+3)(x+2)(x-1)=0
\n" ); document.write( "roots are -3, -2, and +1\r
\n" ); document.write( "\n" ); document.write( "(i) is 14\r
\n" ); document.write( "\n" ); document.write( "(ii) is 36\r
\n" ); document.write( "\n" ); document.write( "(iii) is (-5)(-1)(-2)=-10\r
