Question

Write a equivalent expression to -ab +(-ac)

Answer 1

We are given the following expression:

`-ab+\mleft(-ac\mright)`

We can rewrite the expression by using the sign inside the parenthesis, like this:

`-ab+(-ac)=-ab-ac`

Now, we can take "-a" as a common factor:

`-ab-ac=-a(b+c)`

And thus we get an equivalent expression.
