Answer:
1,2
Explanation:
You want to create a zero in the problem
x^3-x^2-4(x-1)^2=0
To make a zero in this one you would make x a 1 because at the end, 4(1-1)^2 is zero
So the whole problème would be 1^3 - 1^2 - 0 = 0
The you could also factor to find the second solution
So
X^3-x^2-2(x-1)2(x-1)=0
Now you want x=2 because 2^3 -2^2-2^2=0
I hope that makes sense
