Answer 2

Step-by-step explanation:

Rewrite 1 as 12 . Check the middle term by multiplying 2ab 2 a b and compare this result with the middle term in the original expression. Simplify. Factor using the perfect square trinomial rule a2−2ab+b2=(a−b)2 a 2 - 2 a b + b 2 = ( a - b ) 2 , where a=x and b=−1 .
