I believe that,that is the only form you can write it because if you do 7-15 it's -8 so that's the only way that you can write it.
Answer:
Short Answer: B
Step-by-step explanation:
Using synthetic division to break this down a little, we get from your hint, the following
-5 || 1 - 4 -21 100 - 100
-5 45 -120 100
======================
1 -9 24 -20 0 = x^3 - 9x^2 + 24x - 20
We can do this again, this time using 5
5 || 1 - 9 24 - 20
5 -20 20
===========================
1 -4 4 0 = x^2 - 4x + 4
h(x) = x^2 - 4x + 4 factors into
h(x) = (x - 2)(x - 2)
The final result is f(x) = (x + 5)(x - 5)(x - 2) (x - 2)
which is B
Answer: x = 9 is the x-intercept. Step-by-step explanation: We have given the coordinates (-6,10) and (12,-2).
