What is the intermediate step in the form (x+a) ^2=b as a result of completing the square for the following equation? x^2-14x-284=-2x

See the explanation

Step-by-step explanation:

The equation given to us is:

x² - 14x - 284 = - 2x

Lets solve the given equation

x² - 14x + 2x - 284 = 0

x² - 12x - 284 = 0

Lets convert it into whole square, we know that

c²+2cd+d² = (c+d) ² or c²-2cd+d² = (c + (-d)) ²

So

x² - 12x - 284 = 0

x² - 2 (x) (6) + 6² - 6² - 284 = -

(x² - 2 (x) (6) + 6²) - 36 - 284 = 0

(x + (-6)) ² - 320 = 0

(x + (-6)) ² = 320

if a=-6 and b=320, then the equation becomes:

(x + a) ² = b
