find a quadratic equation with roots (4+i) and (4-i)
\n" ); document.write( "-----
\n" ); document.write( "f(x) = (x-(4+i))(x-(4-i))
\n" ); document.write( "---
\n" ); document.write( "f(x) = ((x-4)-i)((x-4)+i)
\n" ); document.write( "---
\n" ); document.write( "f(x) = (x-4)^2 - i^2
\n" ); document.write( "---
\n" ); document.write( "f(x) = (x^2-8x+16 + 1
\n" ); document.write( "f(x) = x^2 - 8x + 17
