Which statement is correct about (p(x)=0x^3+0x^2+0x)?

Answer and explanation

Correct answer: It is the zero polynomial whose degree is not defined

Direct answer: Option C, the zero polynomial whose degree is not defined, is correct. Each displayed term has a zero coefficient: 0x^3 = 0, 0x^2 = 0, and 0x = 0. Their sum is therefore the zero polynomial. Degree is determined by the highest power with a non-zero coefficient. Since there is no non-zero coefficient at any power, no degree can be selected under the standard school definition. Option A is wrong because the x^3 term is actually zero and does not remain in the simplified polynomial. Option B is wrong for the same reason: the x^2 term also vanishes. Option D is wrong because the polynomial is identically 0, not the constant 1. Do not confuse the highest exponent written in an unsimplified expression with the degree after zero terms are removed. Memory cue: cancel all zero-coefficient terms first; if nothing remains, it is the zero polynomial and its degree is undefined.
