Question

i.
Check whether the following are quadratic equations :
1.
x2 - 2x = (-2) (3 - x)
(x - 3)(2x +1) = x(x + 5)
ví.7 x + 3x +1 = (x - 2)^
vii. (x + 2)= 2x (x² - 1)
x2 - 4x2 - x + 1 = (x - 2)
Renrecant the
(x + 1)2 = 2(x - 3)
i. (x - 2)(x + 1) = (x - 1)(x + 3)
V. (2x - 1)(x - 3) = (x + 5)(x - 1)
