What is the constant term of the polynomial \\(3x-2)(x^2+5x-1)\\)?
Answer and explanation
Correct answer: 2
To obtain the constant term, multiply the constant terms of the two factors. They are \\-2\\) and \\-1\\), so the constant term is \\((-2)(-1)=2\\). Choosing \\-3\\) results from an incorrect sign calculation. Exam tip: For a product of polynomials, multiply the constant terms of the factors directly.
