Answer:

(2a-1)^2

Step-by-step explanation:

Rewrite 4a^2 as (2a)^2

.

(2a)^2−4a+1

Rewrite 1

as 12

.

(2a)^2−4a+1^2

Check the middle term by multiplying 2ab

and compare this result with the middle term in the original expression.

2ab=2⋅(2a)⋅−1

Simplify.

2ab=−4a

Factor using the perfect square trinomial rule a^2−2ab+b^2=(a−b)^2

, where a=2a and b=−1

.

(2a−1)2
