Question 52342
Please help and solve this graph for me. y=-x^2-2x 

x;             -3 -2 -1 0 1
y;=-x^2-2x.....-3..0..3.0.-3

graph is given below..blue line..its x intercepts are -2 and 0 ..hence x=0 and x=-2 are the solutions.2 more graphs...green and red lines are plotted here for 
y=x^2 ....green line...and y = -2x....red line whose intersection at x=0 and x= -2 confirm the same solution in another way
