You can put this solution on YOUR website!
As an alternative, you CAN try to work backward from the 'vertex' form into the polynomial form. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Assuming \"a\" is 1, then \"y=%28x-h%29%5E2%2Bk\", for vertex being (h,k).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=x%5E2-2hx%2Bh%5E2%2Bk\", by doing the multiplication and simplification.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This corresponds to \"y=x%5E2%2Bbx%2Bc\".
\n" ); document.write( "You have \"b=-2h\" and \"c=h%5E2%2Bk\".\r
