$\"%28x%5E2%2B2x-8%29\"$ = 0
\n" ); document.write( "(x-2)(x+4)=0 [factor]
\n" ); document.write( ".
\n" ); document.write( "x-2=0 [set each factor equal to zero and solve for the x-value]
\n" ); document.write( "x=2
\n" ); document.write( "and
\n" ); document.write( "x+4=0
\n" ); document.write( "x=-4
\n" ); document.write( ".
\n" ); document.write( "SOLUTION: x = 2 and -4 \n" ); document.write( "
