Depends what you are expected to know or what method you are told to use.
One learns very early on

Seeing you have the difference of two squares,



So the division to perform using this is obvious.


Maybe you want to use polynomial division?
           2x     -3
       ____________________________
2x+3   |   4x^2    0x    -9
           4x^2    6x
         --------------
           0      -6x   -9
                  -6x   -9
                 ---------
                  0    0     remainder 0

You use incorrect button, when you print the  " - "  sign.

In this case,  we still are able to guess correctly,
but in other cases it may lead to critical misunderstanding.


Learn to print your posts correctly and make it with full responsibility.


Learn the buttons in your keyboard.

Tutor @josgarithmetic offers two great methods. Another alternative is synthetic division.

I think the difference of squares method is the most efficient route as shown by tutor @MathLover1
