ok

Answer 10

your equation is
x^2-2x+6=0
now take the constant to RHS
x^2-2x = -6
look to LHS of this equation what should i add to make it perfect square like it become (a+b)^2 or (a-b)^2

Answer 11

ok

Answer 12

so if i add 1 to LHS and RHS then LHS become a perfect square
x^2-2x+1 = -6+1
(x-1)^2 = -5
this LHS has became a perfect square by adding 1 to it
