Looking at the Algorithm
We can see that
A) True
2 is one of the roots and the divisor of that Divison
B) False
When we plug into the function (x) the root the result is going to be zero
Since f(-2) = 5(-2)² -16(-2) +12 f(-2) = 20 +32 +12 f(-2) = 64 not equal to zero, then x = -2 is not the root
f(x) = -5x² -16x +12 has x_1= 2 and x_2= 6/5
C) False
Factoring f(x) = -5x² -16x +12 we'll have f(x) = (5x -6)(x-2)
D) True
For the previous explanation
E) True
Rewriting as a factored form we'll have f(x) = (5x -6)(x-2)/(x-2) = 5x -6
F) False
We can't find the same result as the previous one. by dividing by (x+2)
