Solve x2 - 8x+ 8 = 0 by completing the square,

Step-by-step explanation:

- 8x+ 8 = 0

we divide the coefficient of the X by half :

in this case: 8x/2 = 4 , then we do the following

to the result obtained (4) squared: 4^2=16

we sum and subtract by 16 to maintain the balance of equation:

- 8x+ 16-16+8 = 0

we have:

-16 +8=0

=16-8

= 8

we write the square root on both sides of the equation:

we know:

so we have:

abs(x-4)=

abs(x-4)=2

we have:

finally we have:
