Final answer:
To rewrite the rational expressions as equivalent rational expressions, factor the denominators and find the common factors.
Step-by-step explanation:
To rewrite the rational expressions as equivalent rational expressions, we need to factor the denominators and find the common factors.
- For the expression (6)/(b²+3b-28), the denominator can be factored as (b+7)(b-4).
- For the expression (8b)/(b²-6b+8), the denominator can be factored as (b-4)(b-2).
Therefore, the equivalent rational expression for (6)/(b²+3b-28) is (6)/((b+7)(b-4)) and the equivalent rational expression for (8b)/(b²-6b+8) is (8b)/((b-4)(b-2)).
