Solve x- 8x = 20 by completing the square. which is the solution set of the equation?
o {-22, 14}
o {-14, 22}
o {–10,2}
o {-2, 103

The right question is

now multiply 1/2 by the coefficient of x which is 8

now add square of 4 on both side of equation we will get

taking square root on both sides

we get

so third option is correct

if u find any confusion u can ask me

i hope you will understand it

Thank u
