#x = 4 or x=2#

Assuming your EQN is #x^2 - 6x +8 =0#

To solve the EQN, factorization is applied.

#x^2 - 6x +8 = 0#

⇒ #(x - 4)(x - 2)# #=0#

⇒ #(x-4) = 0# or #(x-2) = 0#

⇒ # x=4 or x=2# √

#x=2 or x=4#

#x^2-6x+8=0=># assuming you need the solution, factor as:

#(x-2)(x-4)=0=># The Zero Product Property: if #ab=0#:

either #a=0# or #b=0# or both, so in this case:

#x-2=0=># #x=2#
or:
#x-4=0=># #x=4#
