4. Find the zero of the polynomial in each of the following cases:
(i) p(x)= x + 5
(ü) p(x)= x-5
(iii) p(x) = 2x + 5
(iv) p(x) = 3x - 2
(v) p(x)= 3x
(vi) p(x) = ax, a 70
(vii) p(x) = cx +d, c#0, c, d are real numbers.​

Answer 1

Answer:

Answers are in the explanation

Step-by-step explanation:

(I) p(x)=x+5

0=x+5

x=-5

(II) p(x)=x-5

0=x-5

x=5

(III) p(x)=2x+5

0=2x+5

2x=-5

x=-5/2

(iv)p(x)=3x-2

0=3x-2

3x=2

x=2/3

(v) p(x)=3x

0=3x

x=0/3

x=0

(vi)p(x)=a, a70

cannot defined for comma

(vii) p(x)=cx+d

0=cx+d

cx=(-d)

x=(-d) /c
