If (p(x)=2x^3+(h-5)x+4) has degree (3), what is correct about (h)?

Answer and explanation

Correct answer: Any real (h)

The degree of a polynomial is the highest power of the variable having a non-zero coefficient. Here, the coefficient of (x^3) is 2, which remains non-zero for every real value of (h). Hence, the polynomial always has degree 3. For (h=5), only the (x) term disappears; the (x^3) term does not. Exam tip: To determine degree, first check the coefficient of the highest-power term.
