Which of the following algebraic expressions is not simplified?

Hunter-Best [27]

Answer:

B. $x+2x$

Step-by-step explanation:

we will verify each options

option-A:

we have

$x+1$

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

$x+2x$

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

so, they are like terms

so, we can combine or simplify it

$x+2x=3x$

So, this expression is not in simplest form

this is TRUE

option-C:

we have

$x^2+x$

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

$5x^3-x$

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
