Given the expression
[tex]x+x+x+2[/tex]
It can be equivalent to the following
a) By adding the like terms, i.e
[tex]x+x+x+2=3x+2[/tex]
b) By adding two like terms and factorizing the common factor, i.e
[tex]\begin{gathered} x+x+x+2=2x+x+2=2x+2+x \\ \text{Factorize the above} \\ x+x+x+2=2x+2+x=2(x+1)+x \\ x+x+x+2=2(x+1)+x \end{gathered}[/tex]
Hence, the answers are A and D
