That will depend upon the situation. Please reply with the full and exact text of the exercise in question, the complete instructions, and a clear listing of what you have tried thus far.

You have posted:

. . . . .$$\displaystyle \large{\mbox{exercise:\,}\,6x^2\,-\,\frac{9x}{-3x}\,=\,\mbox{?}}$$

What are you supposed to do with this exercise? It looks like you're supposed to evaluate for some value of "x" (hence the open-ended "equals" sign at the end), but no value has been provided for "x". Please clarify.

Thank you.
