What is the degree of (0x^4+0x^2+6)?

Answer and explanation

Correct answer: (0)

The direct answer is C, degree 0. Degree is found after removing terms whose coefficients are zero. In the given expression, 0x^4=0 and 0x^2=0, so it becomes 6. The remaining polynomial is the non-zero constant 6, whose degree is 0. Option A, 4, is wrong because the x^4 term has coefficient zero and therefore is not actually present. Option B, 2, is wrong for the same reason: the x^2 term also disappears. Option C is correct because the highest power of x in the simplified non-zero polynomial 6 is 0. Option D, not defined, is wrong because the expression is not the zero polynomial; it equals 6. The degree of the zero polynomial is treated specially, but that rule is irrelevant here. Do not identify degree by looking at the largest exponent before checking coefficients. Memory cue: first delete zero-coefficient terms, then find the highest remaining exponent.
