Answer: Finite Set</h3>
Explanation:
We have a set of x values such that (x-1)(x-2) = 0. Breaking that down leads to either x-1 = 0 or x-2 = 0 through the zero product property. Solving each of those equations gets us x = 1 and x = 2 as the two items in this set.
So the original set your teacher gave you turns into the roster form {1,2}. There are two items in this set and we can see it's a finite set since it does not go on forever. Note that everything in this set is a natural number.
The distance from 0 on the number line represents the absolute value of the number
//You need to factorise the two quadratics and divide where possible
x^2 + 3x + 2 = (x+2)(x+1)
x^2 - 4 = (x+2)(x-2)
y = (x+2)(x+1)/(x+2)(x-2)
y = (x+1)/(x-2)
If every minute 3 poles past and poles are 1/4 mile (0.25 mile) apart;
3x0.25 = 0.75
Train moves 0.75 mile/per minute
If you want the train's speed per hour, then;
x = 60x0.75
x= 45miles per hour is the speed of the train
