BRAINLIESTTTT!!!!

Write x^2 − 2x − 3 = 0 in the form (x − a)^2 = b, where a and b are integers.

(x − 4)2 = 3
(x − 3)2 = 2
(x − 2)2 = 1
(x − 1)2 = 4

we have that
x² − 2x − 3 = 0

Step 1
isolate the variable terms 
x² - 2x = 3 

Step 2
complete the square 
x² - 2x + 1² = 3 + 1² 
(x-1)² = 4 

the answer is the option (x-1)² = 4
