Final answer:
The expression 5kp-15kr-np+3mr is factored as the product of two binomials by grouping terms and factoring out common factors, resulting in (5k - n)(p - 3r).
Step-by-step explanation:
To factor the expression 5kp-15kr-np+3mr as the product of two binomials, we need to group terms and factor out common factors from each group. We can group the terms as follows: (5kp - 15kr) - (np - 3mr). In the first group, the common factor is 5k, and in the second group, the common factor is -n. Factoring these out, we have:
Now we see that (p - 3r) is a common binomial factor, which we can factor out:
So the expression 5kp-15kr-np+3mr factored as the product of two binomials is:
(5k - n)(p - 3r)
