Answer:

Given that: x2+6x+8

                  =x2+4x+2x+8,        (split middle term)

                  =(x2+4x)+(2x+8),    (group pair of terms) 

                  =x(x+4)+2(x+4),         (factor each binomials)

                  =(x+4)(x+2),              (factor out common factor (x+4)

Hence factors of x2+6x+8 are (x+4)(x+2)
