Question

4. Find the zero of the polynomials in each of the following cases:
(i) p(x) = x+5
(11) p(x) = x-5
(iii) p(x) - 2x+5
​

Answer 1

Step-by-step explanation:

p(x)= x+5

x+5=0

x= -5

p(-5)=0

THE ZERO OF THE POLYNOMIAL IS -5

p(x)=x-5

x-5=0

x=5

p(5)=0

THE ZERO THE POLYNOMIAL IS 5

p(x)=2x+5

2x+5=0

2x= -5

x= -5/2

p(-5/2)=0

THE ZERO THE POLYNOMIAL IS -5/2
