Clearly not B, because of the x^2 preceded by 3 (not a problem) but the middle term of 2.4.
\n" ); document.write( "A is prime, because if we complete the square, we have x^2+4x+4=-5+4, and that is (x+2)^2= -1, and x+2=+/- sqrt (-1)
\n" ); document.write( "C factors into (x-3)(x-1)=0. It is C.
\n" ); document.write( "
\n" ); document.write( "
\n" );
