Question

1. Check whether the following are quadratic equations :
(i) (x + 1)2 = 2(x - 3)
(ii) x2 – 2x =(-2) (3 - x)
(iii) (x - 2)(x + 1)=(x - 1)(x+3) ~ (iv) (x - 3)(2x +1)= x(x + 5)
(v) (2x - 1)(x – 3)=(x + 5)(x - 1) x (vi) x2 + 3x + 1 = (x - 2)2X
(vii) (x + 2) = 2x (x2 – 1) v
(viii) x3 – 4x2 - x + 1 = (x - 2)
2. Renresent the followi​

Answer 1

Explanation:

I will do only first part

2x +2=2x-6

8=0

No it is not a quadractic equation
