Can i get explanation on where i made mistake and how to get rid of it?

1,2

Step-by-step 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
