Find the zero (root) of the polynomial in each of the following cases: (i)`h(x)=2x` (ii) `p(x)=c\ x+d ,\ !=0` (iii)`p(x)=a x ,\ a\ !=0`

Explanation

)`h(x)=2x=0`
`=>x=0 `, Therefore , 0 is is zero (root) of h(x).
(ii)`p(x)=c\ x+d ,\ !=0`
`p(x)=c\x+d=0`
`=>c\ x=-d`
`x=-d/c`
Therefore, -d/c is the zero of p(x).
(iii)`p(x)=ax ,\ a\!=0`
`=>p(x)=ax=0`
`=>x=0`.Therefore, 0 is the zero of p(x)
