You can put this solution on YOUR website!
this is a parabola the y intercept is found setting x's value to zero\r
\n" ); document.write( "\n" ); document.write( "so y intercept is 14 or (0,14)\r
\n" ); document.write( "\n" ); document.write( "the x intercepts are found by setting y=0\r
\n" ); document.write( "\n" ); document.write( "so we have \"x%5E2%2B8x%2B14\" using the quadratic formula we come up with x intercepts of -2.59 and -5.41 or (-2.59,0)and (-5.41,0)\r
\n" ); document.write( "\n" ); document.write( "Quadratic equation (in our case ) has the following solutons:\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For these solutions to exist, the discriminant should not be a negative number.\r
\n" ); document.write( "\n" ); document.write( "First, we need to compute the discriminant : .\r
\n" ); document.write( "\n" ); document.write( "Discriminant d=8 is greater than zero. That means that there are two solutions: \r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Quadratic expression can be factored:\r
\n" ); document.write( "\n" ); document.write( "Again, the answer is: -2.58578643762691, -5.41421356237309. :
