Which of the following is a quadratic polynomial in one variable?
Correct Answer: Option(c)
Polynomials in one variable are algebraic expressions that consist of terms in the form 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
Hence the only quadratic polynomial in one variable is the the equation
