Question

1. Check whether the following are quadratic equations :
(i) (x + 1)2 = 2(x – 3)
(i) 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)3 = 2x (x2 – 1)
(viii) x3 – 4x2 – x + 1 = (x - 2)3

Answer 1

Answer:

(i) (x + 2)2 = 2(x - 3)⇒ x2 + 2x + 1 = 2x - 6⇒ x2 + 7 = 0It is of the ... (ii) x^2 - 2x = (-2)(3-x) (iii) (x-2)(x+ 1) = (x-1)(x+3) (iv) (x-3 ..
