What is the intermediate step in the form (x + a)2 = b as a result of completing the square for the following equation?
-3x2 - 36x = 300

we need to add a²=6² to both sides of  in order to rewrite in the form .

Step-by-step explanation:

Given the equation

First of all, we need to divide both sides by -3 to simplify it

i.e.

In order to rewrite in the form , we need to add a²=6² to both sides

so

Therefore, we need to add a²=6² to both sides of  in order to rewrite in the form .

i think it is c, not positive though
