Question

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)
(vi) x2 + 3x + 1 = (x - 2)2
vii) (x + 2) = 2.c (x² - 1)
(viii) x2 - 4x2 - x + 1 = (x - 2)
