For the development of the exercise, we will need to remember some aspects of the factorization cases, specifically, the difference of squares. The first thing to do is to check if our algebraic expression complies with the rules to be able to apply this factorization case:
-Be a binomial
-Be separated by a minus sign.
-Each term must have an exact square root.
As it meets these criteria, we proceed to apply the factorization case as follows
Thus, the factorization for this expression is x^2-25= (x-5)(x+5).
Answer:
<h2>1620 kg</h2>Solution,
Let the length and breadth of smaller rectangle be l and b.
Length and breadth of larger rectangle be 3L and 3 b.
Besides, depth is same in both beds.
As area of small rectangle=180
Area of larger rectangle:
