Question

(y-2) (y+2) =0 is quadratic equation or not​

Answer 1

Step-by-step explanation:

$(y - 2)(y + 2) = 0$

${y}^{2} + \not2y - \not 2y - 2 = 0$

${y}^{2} - 2 = 0$

Since the highest degree in equation is 2, hence it is a quadratic equation

Answer 2

Answer:

yes it is a quadratic equation.

It can be written as y² - 4 = 0 or y² + 0y - 4 = 0 which is in the form of ax² + by + c = 0

Hope you understand it
