(i) p(x) = x – 5
(ii) p(x) = 2x + 5
(iv) p(x) = 3x - 2
(v) P(x)=3x
(vi) p(x) = ax, a=0
(vii) p(x) = cx +d, c#0, c, d are real numbers.​

Answer 2

To find zero of the polynomial, p(x)=0

(i) If p(x)=x+5=0 then x=−5, i.e. −5 is the zero.

(ii) If p(x)=x−5=0 then x=5, i.e. 5 is the zero.

(iii) If p(x)=2x+5=0 then x=−5/2, i.e. −5/2 is the zero.

(iv) If p(x)=3x−2=0 then x=⅔, i.e. ⅔ is the zero.

(v) If p(x)=3x=0 then x=0, i.e. 0 is the zero.

(vi) If p(x)=ax=0 then x=0, i.e. 0 is the zero.

(vii) If p(x)=cx+d=0 then x=−d/c, i.e. −d/c is the zero.
