What are the like terms in the expression 8 + x squared minus 4 x cubed + 5 x + 2 x squared?

See below.

Step-by-step explanation:

So we have the expression:

Like terms are terms in which the variables and the exponents they are in are exactly the same.

In the above expression, the only like terms are x² and 2x². Thus, we can add them:

Step-by-step explanation:

Given Expression is:

"Like terms" are terms whose variables and their exponents are the same.

So, In the given expression, the like terms are:

=>

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
