To factorize the expression (l + m)2 - 4lm, we can follow these steps:

Step 1: Expand the square term (l + m)2 using the formula (a + b)2 = a2 + 2ab + b2.
(l + m)2 = l2 + 2lm + m2

Step 2: Substitute the expanded term back into the original expression.
(l + m)2 - 4lm = l2 + 2lm + m2 - 4lm

Step 3: Combine like terms.
(l + m)2 - 4lm = l2 - 2lm + m2

Therefore, the factorization of (l + m)2 - 4lm is l2 - 2lm + m2.
