Question

Check whether the following are quadratic equations (x+1)²=2(x-3)​

Answer 1

Step-by-step explanation:

Hence it is quadratic equation but it is not in form of ax^2+bx+c=0

Answer 2

Yes

(x+1)^2 = 2(x-3)

x^2 + 2x + 1 = 2x - 6

x^2 + 2x - 2x + 1 + 6 = 0

x^2 + 7 = 0

The maximum index of this equation is 2. Therefore it is a quadratic equation
