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.
