Question

1. Check whether the following are quadratic equations :
(i) (x - 2)^2 + 1 = 2x - 3
(ii) x (x + 1) + 8 = (x + 2) (x - 2)
(iii) x (2x + 3) = x^2 + 1
(iv) (x + 2)^3 = x^3 - 4
(v) (2x - 1) (x – 3) = (x + 5) (x - 1)
(vi) x^3 - 4x^2 - x + 1 = (x - 2)^3
(vii) x = 2-1/x^2
(viii) x^4 + 4 = 7x - 3x^2
(ix) 16x^2 - 3 = (2x + 5) (5x - 3)
(x) x + 3/X=x^2​
