What is the intermediate step in the form (x+a)^2 = b as a result of completing the square for the following equation? 5x^2 - 360 = -60x

Assuming you are speaking of the Real Numbers…

x^2+66=14x+15

x^2 - 14x + ?? = -51

x^2 - 14x + (half of -14 squared) = -51 + (half of -14 squared)

x^2 - 14x + 49 = -51 + 49

(x - 7)^2 = -2

By the way, in the real number system, you can’t square any number and get a negative so the above equation has no solution. If you allowed for complex solutions…there would be two of those.

Sorry don't know the answer.

this is very long be shot question
