Verify whether the following are zeros of the polynomial , Indicted against them , or not,
(i) ` p(x) =2x-1, x=(1)/(2) `
(ii) ` p(x) =x^(3) -1 , x=1`
(iii) ` p(x) =ax +b, x = (-b) /( a ) `
(iv) ` p(x) =( x+3) (x-4) , x = -3 ,x =4`

Text Solution

Verified by Experts

The correct Answer is:
` therefore ( 1)/(2) ` is the zero of the polynomial
(ii) ` therefore 1` is the zero of the polynomial
(iii) ` therefore (-b)/(a) ` is the zero of the polynomial
` therefore -3 ` and 4 are the zero of the polynomial
