Answer 2

A)(x-1)²
(x-1)(x-1)
x²-x-x+1
x²-2x+1

B)(a-2)²
(a-2)(a-2)
a²-2a-2a+4
a²-4a+4

c)(4x-1)²
(4x-1)(4x-1)
16x²-4x-4x+1
16x²-8x+1

D)(2a-5b)²
(2a-5b)(2a-5b)
4a²-10ab-10ab+25b²
4a²-20ab+25b²

e)(n-√6)²
(n-√6)(n-√6)
n²-√6n-√6n+√36
n²-2√6n+6

F)(2n-1)²
(2n-1)(2n-1)
4n²-2n-2n+1
4n²-4n+1

g)(3a-2b)²
(3a-2b)(3a-2b)
9a²-6ab-6ab+4b²
9a²-12ab+4b²

h)(2ab-c)²
(2ab-c)(2ab-c)
4a²b²-2abc-2abc+c²
4a²b²-4abc+c²
