Question

is quadratic or not.
EXERCISE 10.1
1. Check whether the following are quadratic equations:
(i) x-2x=(-2) (3 – x)
() (x + 1)2 = 2(x-3)
(ii) (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
sal (vii) (x+2) = 2x (x2 - 1)
(viii) x - 4x2 - x + 1 = (x - 2)
