Question

(iv) p(x)=(x + 1) (x - 2); x=-1,2​

Answer 1

Answer:

x = 0 in first case

x= 0 in second case

both are zero of p(x) polynomial

Answer 2

Answer:

if x=2 then the answer is 0

if x=-1 then the answer is 0.

Because any number multiplied by zero is zero

Step-by-step explanation:

p(-1)=(-1+1) (-1-2)=0

p(2)=(2+1) (2-2)=0
