An equation of degree 2 is called quadratic equation.
(A) Degree of given expression is 3.
So. its not quadratic
(B) Degree of given equation is 1,
So, its not quadratic.
(C) Degree of this equation is 2
So, its quadratic equation.
(D) y(y+2) = y² + 3y
⇒ y² + 2y = y² + 3y
⇒ 2= 3y
⇒y = 0
Hence. its also not quadratic
