Question

verify whether the values of x given is zero of the ponlynomial or not?
p(x) = ax + b ; x =-b/a
​

Answer 1

Answer:

p(x) =ax+b

p(-b/a) =a(-b/a) +b

p(-b/a) =-b+b=0

Answer 2

Answer:

-b/a is a zero

Step-by-step explanation:

p(-b/a)=a*-b/a+b

          = -b+b

          =0

hence -b/a is a zero of polynomial p(x) because when we replace x with -b/a we get 0 as result.
