Answer:
x^2 -x -2 = (x -2)(x +1)
Step-by-step explanation:
To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:
-2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1
Then these are the constants in the binomial factors:
x^2 -x -2 = (x +1)(x -2)

<em>Comment on the question</em>
The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.
Answer:
the slope would be 3
Step-by-step explanation:
the slope would be 3 because the slope is change in y divided by change in x
is y goes up 3 y goes up 1
3/1=3 so the slope is 3
Answer:
D. Yes,because every x-value corresponds to exactly one y-value.
Step-by-step explanation:
The given ordered pairs are;
{
}
We do not have the same x-value corresponding to more than one y-value.
We can see from the ordered pairs that every x-value corresponds to exactly one y-value.
Therefore the graph of this relation will pass the vertical line test.
