Answer:
The roots are: √11 + 2 and -√11 + 2
Explanation:
First, we would put the equation in the standard form which is as follows:
ax² + bx + c = 0
This can be done as follows:
x² - 4x + 4 - 11 = 0
x² - 4x - 7 = 0
By comparison:
a = 1
b = -4
c = -7
Now, to get the roots, we would use the quadratic equation shown in the attached image.
By substitution, we would find that:
either x = √11 + 2
or x = -√11 + 2
Hope this helps :)

Answer: Choice A. 4 times
========================================================
Explanation:
We'll be using this formula
to compute the average rate of change (AROC) from x = a to x = b. Note how this is effectively the slope formula because y = f(x).
To start things off, we'll compute the AROC from x = 1 to x = 2.
Do the same for the AROC from x = 3 to x = 4.
The jump from m = 10 to m = 40 is "times 4", which is why choice A is the final answer.
