Final answer:
To factor the expression completely, we can rewrite it as (10b + 3)(b - 1) and (10b - 1)(b + 3).
Step-by-step explanation:
To factor the expression completely, we need to find two binomial factors that multiply to give us the original expression. In this case, the expression is 10b^2 + 17b + 3.
We can start by looking for two numbers whose product is 10 x 3 = 30 and whose sum is 17. The numbers that satisfy these conditions are 10 and 3. So, we can rewrite the expression as (10b + 3)(b + 1).
The correct answer is option d) (10b + 3)(b - 1) and (10b - 1)(b + 3).
