Question

what is 2x+x and what is 2x*x​

Answer 1

Answer:

2x+x=3x

2x×x=2x square

Answer 2

Step-by-step explanation:

First of all I would appreciate your question and I am glad to answer the same. If we see carefully 2x-x is just an algebraic expression

Case 1 : If f(x) = 2x-x, then it is a polynomial. That's also a linear polynomial. If you put x=c (say) then f(c) = 2c-c

Case 2 : If 2x-x = 0 then this is no more a polynomial, it becomes an equation. In this case it is a linear equation. The value of x is 0 in this case.

x(2-1) = 0

Therefore, x = 0.
