Write a quadratic function having the given zeros: 6, -2
\n" ); document.write( "

\r\n" );
document.write( "This is a problem where you are given the answers and you\r\n" );
document.write( "want to find the question.  First I'll give you the function,\r\n" );
document.write( "f(x) = x²-4x-12 and solve it, then show you how to get it: \r\n" );
document.write( "\r\n" );
document.write( "x²-4x-12=0\r\n" );
document.write( "(x-6)(x+2)=0\r\n" );
document.write( "x-6=0  x+2=0\r\n" );
document.write( "  x=6    x=-2\r\n" );
document.write( "\r\n" );
document.write( "Now here's how to get that function.  Just reverse the steps\r\n" );
document.write( "above and you'll see:\r\n" );
document.write( "\r\n" );
document.write( "  x=6    x=-2\r\n" );
document.write( "x-6=0  x+2=0\r\n" );
document.write( "(x-6)(x+2)=0\r\n" );
document.write( "x²-4x-12=0\r\n" );
document.write( "\r\n" );
document.write( "So the function is f(x) = x²-4x-12.\r\n" );
