Solve each polynomial equation by factoring
\n" ); document.write( "x^3+2x^2-9x-18=0.
\n" ); document.write( "x^2(x+2)-9(x+2)=0
\n" ); document.write( "(x+2)(x^2-9)=0
\n" ); document.write( "x+2=0
\n" ); document.write( "x=-2
\n" ); document.write( "x^2-9=0
\n" ); document.write( "x^2=9
\n" ); document.write( "x=±√9=±3 \n" ); document.write( "
