Find the values of​ a, b, and c for which the quadratic equation has the solutions 9i and -9i.
\n" ); document.write( "-------------------
\n" ); document.write( "(x - 9i)*(x + 9i) = x^2 + 81
\n" ); document.write( "----
\n" ); document.write( "a = 1, b = 0, c = 81
\n" ); document.write( "or,
\n" ); document.write( "a = k, b = 0, c = 81k where k = a constant.
\n" ); document.write( "
\n" );
