Which of the following algebraic expressions is not simplified?

B.

Step-by-step explanation:

we will verify each options

option-A:

we have

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

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

so, they are  like terms

so, we can  combine or simplify it

So, this expression is not in simplest form

this is TRUE

option-C:

we have

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

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

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.
