Since one root is -4, then x+4 must divide the polynomial
\n" ); document.write( ":
\n" ); document.write( "(x^2 -3x +k -2)/(x+4) = x-7 with remainder k +26
\n" ); document.write( ":
\n" ); document.write( "we know the remainder must be 0, then
\n" ); document.write( ":
\n" ); document.write( "k +26 = 0
\n" ); document.write( ":
\n" ); document.write( "k = -26
\n" ); document.write( ":
\n" ); document.write( "
