Answer 1

Answer:

Question 1 Check whether the following are quadratic equations:

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

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

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

(viii) x^3 - 4x^2 - x + 1 = (x-2)^3
