Question

Find p(0),p(1),p(-1) and p(-1) for each

1).p(y)=(y-1)(y+1).

Answer 1

Step-by-step explanation:

If y=0

P(0)= (0-1)(0+1)

= 0

P(1)=(1-1)(1+1)

=0*2=0

P(-1)=(-1-1)(-1+1)

=( - 2) 0

=0

Answer 2

Answer:

• first put y=(0)
• (0-1)(0+1)=(-1)*(1)=(-1)
• second put y =1
• (1-1)(1+1)=(0)*(2)=0
• PUT Y =-1
• (-1-1)(-1+1)=(-1)(0)=0
