Order of operations is known as PIMDAS P(Parenthasis) I(Integers) M(Multiplication or Division which ever comes first) (A) (S)Addition and subtraction are last same rule. Whichever one comes first after all other higher steps are acheived.
its terminating because as you can see there isn't any numbers that are ongoing
Answer:

Step-by-step explanation:
We'll write the polynomial using only the roots required to simplify calculations. However, it states the final answer should not have a radical or complex number in. Therefore, we need to rid them:

Expanding this, we get:
.
4 hours equals 12 miles
1 hour equals 3 miles
Replace f(x) with 0. Then solve for x
f(x) = x^2 + 5x - 14
0 = x^2 + 5x - 14
x^2 + 5x - 14 = 0
(x+7)(x-2) = 0 ... factor (think of two numbers that multiply to -14 and add to 5)
x+7 = 0 or x-2 = 0
x = -7 or x = 2
The two zeros, roots, or x intercepts are x = -7 or x = 2
Answer: Choice C) {2, -7}
