If (p(x)=3x-4), what type of polynomial is (p(x)-3x)?
Answer and explanation
Correct answer: Constant polynomial
Given p(x)=3x-4, p(x)-3x=(3x-4)-3x=-4. Since -4 is a non-zero constant and contains no term in x, it is a constant polynomial. It is not a zero polynomial, because a zero polynomial must equal 0. Exam tip: simplify first, then identify the polynomial type from the degree of the remaining expression.
