# Which of the following is not a quadratic equation?A. 3x – x2 = x2 + 5B. (x + 2)2 = 2(x2 – 5)C. (√2x + 3)2 = 2x2 + 6D. (x – 1)2 = 3x2 + x – 2

A.   This is a quadratic equation of the form hence i.e. of degree 2 (a ≠ 0, a, b, c are real numbers).

B.  using   This is a quadratic equation of the form i.e. of degree 2 (a ≠ 0, a, b, c are real numbers).

C. using   This is not quadratic since it is not of the form i.e. of degree 2 (a ≠ 0, a, b, c are real numbers).

D.  using   This is a quadratic equation of the form i.e. of degree 2 (a ≠ 0, a, b, c are real numbers).
