Answer :
Answer:
Step-by-step explanation:
To simplify the rational expression (25b^2 + 40b + 16) / (5b + 4), we first need to factor the numerator and denominator.
The numerator can be factored as (5b + 4)(5b + 4), which simplifies to (5b + 4)^2.
The denominator is already in its simplest form as 5b + 4.
Therefore, the simplified form of the rational expression is (5b + 4)^2 / (5b + 4).
