The curve below has a horizontal tangent line at the point
( − 4 , 7 ) \displaystyle {\left(-{4},{7}\right)} ( − 4 , 7 ) and at one other point. Find the coordinates of the second point where the curve has a horizontal tangent line.
25 x 2 + 200 x + 4 y 2 − 16 y = − 316 \displaystyle {25}{x}^{{2}}+{200}{x}+{4}{y}^{{2}}-{16}{y}=-{316} 25 x 2 + 200 x + 4 y 2 − 16 y = − 316 x \displaystyle {x} x -coordinate of second point =
