What is the intermediate step in the form square for the following equation? (x + a) ^ 2 = b as a result of completing the square for the following equation? - 3x ^ 2 - 33x + 45 = 9x

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
