-6x-6=x²-5x-6
x²+x=0
x(x+1)=0
x=0, x=-1
x=0, y=-6x-6=-6*0-6=-6 (0,-6)
x=-1, y=-6x-6=-6*(-1)-6=0 (-1,0)
Answer (-1.0) and (0,-6) . The last one.
Check
(0,-6), y=-6-x, -6=-6-0, -6=-6 True
y=x²-5x-6, -6=0+0-6, -6=-6, True
(-1,0),y=-6-x, 0=-6-(-6), 0=0 True
y=x²-5x-6, 0=1²-5(-1)-6=1+5-6=6-6=0, 0=0 True,
So,
Answer (-1.0) and (0,-6) . The last one.
