If k is the constant in the expression x^2 – x + k and the expression has a
\n" ); document.write( "value of 0 when 3 is substituted for x, what is the value of the expression when 2 is substituted for x?
\n" ); document.write( "----------------------------------------\r
\n" ); document.write( "\n" ); document.write( "Find K
\n" ); document.write( "3^2 - 3 + k = 0
\n" ); document.write( "9-3 + k = 0
\n" ); document.write( "6+k = 0
\n" ); document.write( "k = -6
\n" ); document.write( "--------
\n" ); document.write( "Let x = 2
\n" ); document.write( "x^2 - x -6 = ?
\n" ); document.write( "2^2-2-6 = ?
\n" ); document.write( "? = -4
\n" ); document.write( "====================
\n" ); document.write( "Ans: -4
