Verify whether the following are zeroes ...

Verify whether the following are zeroes of the polynomial, indicated against them.(i) `p(x)=3x+1, x=-1/3` (ii) `p(x)=5x-pi, x=4/5` (iii) `p(x)=x^2-1, x=1,-1`(iv) `p(x)=(x+1)(x-2), x=-1,2` (v) `p(x)=x^2, x=0` (vi) `p(x)=l x+m, x=-m/l`

Text Solution

Verified by Experts

(i) `p(0) = 3x+1=0`
`x=-1/3` correct
(ii) `p(0) = 5x - pi = 0`
`x= pi/5` incorrect
(iii) `p(0) = x^2 - 1=0`
`x^2 = 1`
`x= -1,1` correct
(iv) `p(0) = (x+1)(x-2) = 0`
