\n" ); document.write( "Find the equation of the curve by using the integration method with the gradient of the curve is 2x^2 - 5x. The point (3, 8) lies on the curve.
\n" ); document.write( "Hence, find the stationary value of this curve on the point (3, 8).

given:\r
\n" ); document.write( "\n" ); document.write( "the gradient of the curve: \"dy%2Fdx=+2x%5E2+-+5x\"
\n" ); document.write( " the point (\"3\",\"+8\")\r
\n" ); document.write( "\n" ); document.write( "since gradient is function degree\"+2\", we are looking for function degree \"3\"\r
