Polynomials

1. What is the degree of the polynomial 5x³ - 4x² + x - 2?

The degree is the highest power of the variable, which is 3 here. So, the degree of the polynomial is 3. A strong exam answer should also explain how this point connects with Definition of polynomial and its terms, include one supporting event from the chapter, and end with a clear sentence showing the lesson learned.

2. How can students understand Definition of polynomial and its terms easily?

Students can first listen to the related audio explanation, then revise the key points and solve practice questions based on this topic. A strong exam answer should also explain how this point connects with Definition of polynomial and its terms, include one supporting event from the chapter, and end with a clear sentence showing the lesson learned.

3. How can Definition of polynomial and its terms be used in exams?

Students can mention the meaning, one example from the chapter, and one clear conclusion to write a complete answer. A strong exam answer should also explain how this point connects with Definition of polynomial and its terms, include one supporting event from the chapter, and end with a clear sentence showing the lesson learned.

4. Write the general form of a quadratic polynomial and explain the condition on coefficients.

The general form is ax² + bx + c, where a ≠ 0. This ensures the polynomial is quadratic, as the x² term must be present. A strong exam answer should also explain how this point connects with Degree of a polynomial and how to find it, include one supporting event from the chapter, and end with a clear sentence showing the lesson learned.

7. If p(x) = x² - 3x - 4, find p(2) and determine if 2 is a zero of the polynomial.

p(2) = 2² - 3×2 - 4 = 4 - 6 - 4 = -6, which is not zero. So, 2 is not a zero of the polynomial.
