Given that the polynomial is divisible by x + 2.
That means x + 2 is a factor.
=> x = -2 is a root
Therefore,

Given x + 1 is a factor.
That means x = -1 is a root
Therefore,
The depth of the water at the end of a pier changes peri along with the movement depth 12.009 am or two
It went from 54 meters above the surface to 9 meters below the surface...
54 to the surface (0) = 54....from 0 to -9 = 9....so it fell (54 + 9) = 63 meters.
so if it fell 63 meters in 35 seconds, then it fell (63/35) = 1.8 meters per second <===
By equating both quadratic equations, Brian can determine the point of intersection of both equations. Upon graphing he was able to identify that both share the same vertex but of opposite opening. Based on this, he can say that both equations are equations of parabolas with same vertex but open on different directions.
