Are \(x^2\) and (x) like terms?
C. नहीं क्योंकि (x) की घात अलग हैNo because the power of (x) is different
समान पदों में चर की घात भी समान होनी चाहिए। \(x^2\) और (x) में घात अलग है। / In like terms, the power of the variable must also be the same. \(x^2\) and (x) have different powers.

What is the simplified form of (0x+9)?
D. (9)
(0x=0), इसलिए (0x+9=9)। शून्य से गुणा करने पर पद शून्य हो जाता है। / (0x=0), so (0x+9=9). Multiplying by zero makes the term zero.
