Question

X squared can be combined with X
true or false

Answer 1

Answer:

False, assuming "combined" means "added or subtracted and would simplify."

$x^2$ and $x$ cannot be combined with addition or subtraction.  They are not like terms.

Step-by-step explanation:

Combining like terms only works if the variables and the powers on the variables match perfectly.  

Examples:

$x^2$ and $x$ don't have matching powers, so they're not like terms.

$x^2$ and $y^2$ have the same powers, but the variables don't match, so they're not like terms.

Anything can be multiplied together though.  So that's a different situation.
