Divisor of polynomial: x + 4, so x = - 4. 
\n" ); document.write( "\"f%28x%29+=+4x%5E6+-+64x%5E4+%2B+x%5E2+-+18\"
\n" ); document.write( "From remainder theorem, \"f%28-+4%29+=+4%28-+4%29%5E6+-+64%28-+4%29%5E4+%2B+%28-+4%29%5E2+-+18\" ----- Substituting - 4 for x to determine remainder
\n" ); document.write( "\"f%28-+4%29+=+4%284096%29+-+64%28256%29+%2B+16+-+18\"
\n" ); document.write( "f(- 4) = 16,384 – 16,384 + 16 - 18
\n" ); document.write( "f(- 4), or remainder is: \"highlight_green%28-+2%29\"
\n" ); document.write( "Since there's a remainder of - 2 when x + 4 is used as a factor, or when x = - 4, then x + 4 is NOT a factor.
\n" ); document.write( "Remainder should be 0 (zero) for a polynomial to be considered a factor of another polynomial. \n" ); document.write( "
