Find the coordinates of the points of itersection A and B of the line 2x+y+2=0 and the curve 1/x +2/y= 1/2
i reform the eqn of the line to be y=-2-2x and the curve is y=
then i sub the two eqn and i 2=(0.5-1/x)(-2-2x)
and so x=-2. but i only got one ans and the qn say there are two point of intersection. How to solve this qn?
