Question

Plz answer question 4 and 5​

Answer 1

Answer:

yes it is a zero polynomial

Step-by-step explanation:

=> (x)^2 +x-20

=> g(x)=-5

=> (-5)^2 -5-20

=> 25-25

=> 0

Answer 2

Answer:

Q.4

let -5 be a zero of p(x)

so,

x=-5

putting value of x in p(x).

(-5)^2 + -5 - 20 = 0

25-25 = 0

0 = 0

so, our assumptions is right and -5 is a zero of p(x).
