Step-by-step explanation:
There is 1 root at x = 1, where the function crosses the x-axis.
There are 2 roots at x = -2, where the function touches the x-axis but does not cross.
So there are 3 real roots total.
The function is:
y = (x − 1) (x − (-2))²
y = (x − 1) (x + 2)²

Answer:
32/13
Step-by-step explanation:
Please include the instructions when you post a problem.
Let's assume you re to simplify this expression.
We get:
-4+2(-2+5)^2 -4 + 2(3)^2 -4 + 36
__________ = ------------------- = ----------------- = 32/13
5-(2-4)^3 5 - (-2)^3 5 + 8
