Answer:

B. [tex]x+2x[/tex]

Step-by-step explanation:

we will verify each options

option-A:

we have

[tex]x+1[/tex]

we can see that x and 1 are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

option-B:

we have

[tex]x+2x[/tex]

we can see that 2x and x are same type of terms

so, they are  like terms

so, we can  combine or simplify it

[tex]x+2x=3x[/tex]

So, this expression is not in simplest form

this is TRUE

option-C:

we have

[tex]x^2+x[/tex]

we can see that x^2 and x are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

option-D:

we have

[tex]5x^3-x[/tex]

we can see that 5x^3 and x are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE
