Question

verify whether the following are zeroes of the polynomial indicated against them

a. P(x)= 3x+1, x = -1/3

b. P(x) = x2

-1, x = -1,1

c. P(x) = 2x+1, x = -1/2

d. P(x) = x2

, x = 0​

Answer 1

Answer:

a. P(x)= 3x+1

solution= 3×-1/3+1=-1+1=0

yes -1/3 is the zero of above polynomial

b. P(x)=x^2-1

i. -1=x

(-1)^2-1=0

-1 is a zero of polynomial x^2-1.

1^2-1=0

1 is also a zero of polynomial x^2-1

c. 2x+1, x= -1/2

= 2×(-1)/2 +1 =0

-1/2 is a zero of polynomial 2x+1

d. x^2= 0^2=0

0 is zero of polynomial x^2.
