\n" ); document.write( "\n" ); document.write( "Presuming you mean to ask if the trinomial can be factored over the rational numbers, the answer is no.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Consider the discriminant, that is the part of the quadratic formula under the radical,

, which is NOT a perfect square. A trinomial is factorable over the rationals if and only if the discriminant is a perfect square.\r
