What is $\"a%5E2%2B2\"$ if a is the smallest root of $\"x%5E2-3x-18\"$ ?
\n" ); document.write( "Factor the trinomial:
\n" ); document.write( "(x + 3)*(x - 6)
\n" ); document.write( "So x = -3, 6
\n" ); document.write( "-3 is the smallest
\n" ); document.write( "Sub -3 for a
\n" ); document.write( "(-3)^2 + 2
\n" ); document.write( "= 11
\n" ); document.write( " \n" ); document.write( "

\n" );
