Final answer:
In the factored expression (a - 2x)(l²m - rp²), the expression (2x - a) gets rearranged to (a - 2x). This is because factoring an expression involves finding common factors and rearranging them in a way that allows us to factor out those common factors.
Step-by-step explanation:
In the factored expression (a - 2x)(l²m - rp²), the expression (2x - a) gets rearranged to (a - 2x). This is because factoring an expression involves finding common factors and rearranging them in a way that allows us to factor out those common factors.
In this case, the common factor is (2x - a), and when factored out, it becomes (a - 2x).
