Step-by-step explanation:
<h2><u>Given :-</u></h2>
x-1-(x-1)²+ax-a
<h2><u>To find :-</u></h2>
Factorize the expression ?
<h2><u>Solution :-</u></h2>
Given expression is x-1-(x-1)²+ax-a
It can be written as
(x-1)-(x-1)²+(ax-a)
=> (x-1)-(x-1)(x-1)+a(x-1)
=> (x-1)[1-(x-1)+a]
=> (x-1)(1-x+1+a)
=> (x-1)(2-x+a)
<h2><u>Answer:-</u></h2>
x-1-(x-1)²+ax-a = (x-1)(2-x+a)
Hope this helps!!

Okay I am not 100% sure because that is an extremely confusing question. But here is what I got.
(A) 2c² = 2bc + ac/2 Given
(B) 4c² = 2bc + ac Multiplication and Distribution
(C) 4c = 4b + a Division and Distribution
(D) 4c - a + 4b Subtraction
(E) 4b = 4c - a Symmetric
