Answer:
The value of the above expression is 0.
Given: Given expression is x²-2x+1.
To find: We have to find its value when x is equal to one.
Solution:
The expression is x²-2x+1.
It is a trinomial expression as it has three terms.
The given value of x is 1.
Thus putting the value of x in the above expression we get-
Thus the value of the above expression is 0.

Verified answer
We are given :-x² + 2x + 1 When x = -1 / 2
Substituting x = -1 / 2 in the equation we get :-
( -1 / 2 )² + 2 ( -1 / 2 ) + 1
( 1 / 4 ) - 1 + 1
1 / 4
Hence This Is your answer
Or if you want to find the second root then make the equation equal to 0 :-
x² + 2x + 1 = 0
x² + x + x + 1 = 0
x ( x + 1 ) + 1 ( x + 1 ) = 0
( x + 1 ) ( x + 1 ) = 0
Case 1 Case 2
x + 1 = 0 x + 1 = 0
x = -1 x = -1
Hence the other root of the equation is -1
Hope it helps
Take care!!!
