@Anonomoose please explain.Thanks!

Answer 3

Please use parentheses to reduce the ambiguity in your statement.

For example, do you mean (4a+12) / (a+3), or (4a+12) / a + 3, or what?

Please get into the habit of using parentheses freely for added clarity.

Once you've made these changes, look at the question again. Which value(s) may "a" not have? Why?
