Factor completely. If the polynomial cannot be factored, write ʺprime.ʺ
-$$x ^ { 2 } - 2 x + 1$$
A) $( x + 1 ) ( x - 1 )$
B) $( x + 1 ) ^ { 2 }$
C) $( x + 2 ) ( x - 2 )$
D) $( x - 1 ) ^ { 2 }$

Question

Quizplus · Accepted Answer

The polynomial is a perfect square trinomial since it can be written as $(x-1)^2$. Thus, it cannot be factored further. Therefore, the answer is (D) $(x-1)^2$.

Factor Completely x2−2x+1x ^ { 2 } - 2 x + 1x2−2x+1

Factor Completely $x ^ { 2 } - 2 x + 1$
