What is the constant term of the polynomial \\(4x+3)(x^2-2x+5)\\)?
Answer and explanation
Correct answer: 15
The constant term is the term that contains no \(x\). In the product, it is obtained only by multiplying the constant terms: \(3\times5=15\). Therefore, the correct answer is 15. The value 5 is the constant term of only the second factor, not of the complete product. Exam tip: To find the constant term of a product, multiply the constant terms of its factors.
