Question

Q5. Which of the following is quadratic polynomial?
A.x+2 B.x2+2 C.x3+2 D.2x+2​

Answer 1

Answer:

B) x2+2

Step-by-step explanation:

Polynomials in one variable are algebraic expressions that consist of terms in the form ax+n

where n is a non-negative (i.e. positive or zero) integer and a is a real number and is called the coefficient of the term. The degree of a polynomial in one variable is the largest exponent in the polynomial.

And for quadratic polynomial n=2.

Hence the only quadratic polynomial in one variable is the the equation X2+2
