Verify whether the values of x given in each case are the zeroes of the polynomial or not ?
(i) `p (x) = 2 x + 1,x =- 1/2`
(ii) `p (x) = 5x -pi , x = (-3)/(2)`
(iii) `p (x) = x ^(2) -1 , x = pm 1`
(iv) `p (x) = (x-1) (x +2) , x =-1,-2`
(v) ` p (y) = y ^(2) , y =0`
(vi ) `p (x) = ax + b, x =- (b)/(a)`
(vii) `f (x) = 3x ^(2) -1 , x =- (1)/(sqrt3) , (2)/(sqrt3)`
(viii) `f (x) =2x -1 , x = (1)/(2), (-1)/(2)`
