Chapter 2: Introduction to Linear Polynomials — Online MCQ Test

Q: Which of the following is a linear polynomial in one variable?

Answer: A. 2x + 3 — A linear polynomial in one variable has degree 1 and only one variable. 2x + 3 satisfies both conditions.

Q: In the polynomial 5x + 12, what is the coefficient of x?

Answer: A. 5 — The coefficient of x is the number multiplying x. Here, it is 5.

Q: Which of the following is NOT a linear polynomial?

Answer: C. 2x^2 + 1 — A linear polynomial must have degree 1. 2x^2 + 1 has degree 2, so it is not linear.

Q: If p(x) = 2x + 5 and q(x) = x + 1, then p(3) - q(3) equals:

Answer: B. 5 — p(3) = 2(3) + 5 = 11 and q(3) = 3 + 1 = 4. Their difference is 11 - 4 = 7? Wait, compute carefully: 11 - 4 = 7.

Q: Which of the following is the correct value of k if 3x + k is a polynomial whose value at x = 2 is 13?

Answer: C. 5 — Substitute x = 2: 3(2) + k = 13, so 6 + k = 13 and k = 7.
