What is the equation you are solving?
Answer:
x= 6 ± √31
Step-by-step explanation:
x^2-12x=-5
x^2 -12x +36= -5 +36
(x -6)^2= 31
√(x -6)^2= ±√31
(x-6)= ±√31
x= 6 ± √31
Not sure sorry edit : oh sorry I was suppose to add this in the comment section
15 - natural (1,2,3...15....) and integers (...-2,-1,0, 1,2,...15,...)
