Answer:
YES
Step-by-step explanation:
The equation, , would be an identity if the equation remains true regardless of the value of x we choose to plug in into the equation.
Let's find out if we would always get a true statement using different value of x.
✍️Substituting x = 1 into the equation:
(TRUE)
✍️Substituting x = 2 into the equation:
(TRUE)
✍️Substituting x = 3 into the equation:
(TRUE)
Therefore, we can conclude that the equation, , is an identity.
