If (p(x)=5x^3+0x^2+0x-12), how many non-zero terms are there in (p(x))?

Answer and explanation

Correct answer: 2

A non-zero term in a polynomial has a coefficient that is not zero. Here, \(5x^3\) has coefficient 5 and the constant term \(-12\) has coefficient \(-12\), so both are non-zero terms. The terms \(0x^2\) and \(0x\) have coefficient 0 and do not contribute any term to the polynomial. Therefore, there are 2 non-zero terms. Exam tip: Remove terms with zero coefficients before counting terms.
