MAYBE GRAPHING THESE 2 EQUATIONS WOULD HELP:
Y=-2X^2-2X (RED CURVE)
Y=X^2-1 (GREEN CURVE)
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+-2x%5E2+-2x%2C+y+=+x%5E2+-1%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = -2x^2 -2x and y = x^2 -1).
first equation:
x-----y
0-----0
1---(-4)
(-1)--0
3---(-24)
second equation
x-----y
0----(-1)
1-----0
(-1)--0
3-----8
