andrew-mc [135]

Answer:

-5(x+6)

Step-by-step explanation:

We are asked to write an expression that is the product of two factors and is equivalent to -5x-30.

We can see that greatest common factor of both terms is 5 as 5 times 6 is equal to 30.

Let us factor out negative 5 from both terms as:

-5(x+6)

Since the expression is product of two factors, therefore, our required expression would be -5(x+6).
