Question

Among the given polynomials is a quadratic polynomial.

• A. 6x – 15
• B. $4x^3–3x$
• C. $x^2–x+1$
• D. $3+4x–7x^4$

Answer 1

The correct option is C $x^2–x+1$

$3+4x–7x^4$ is a polynomial of degree 4, so it is not a quadratic polynomial.

6x – 15 is not a polynomial of degree 2, so it is not a quadratic polynomial.

$4x^3–3x$ is a polynomial of degree 3, so it is not a quadratic polynomial.

$x^2–x+1$ is a polynomial of degree 2, so it is a quadratic polynomial.
