More values are required to solve this question since there are only two unknowns given. To solve this equation, there has to be only a single unknown value. In this example, assuming x is 0,
0 = y2 + 2y
0 = y (y+2)
y = 0 or y+2 = 0
y = 0 pr y = -2
Therefore, in this case, the points of intersection are (0,0) and (0,-2)
If x=y
Y = y2 + 2y
0 = y2 + y
0 = y(y+1)
y = 0 or y+1 = 0
y = 0 or y=-1
When y=0
x=0
When y=-1
x=-1
Therefore, in this case, the points of intersection are (0,0) and (-1,-1)
Note: to solve quadratic equations, cubic equations or any equation with any unknowns not to the power of 1, you must get a value of 0 on one side of the equation before you can get the final values.
