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)
How(vi) x² + 3x + 1 = (x - 2)
Krii) (x + 2)2 = 2x (x2 - 1)
(viii) x3 - 4x2 - x + 1 = (x - 2)3

Answer 1

Answer:

see firstly bring them into simple equation and then see the degree of the equation if it is 2 then it is the quadratic equation.

hope it helped you!!!!!!????
