Answer:

 - 3

Step-by-step explanation:

p(x) =  {x}^{2}  - 2x - 3 \\  \\ p(3) =  {3}^{2}  - 2(3) - 3 = 9 - 6  - 3 = 0 \\  \\ p( - 1) =  {( - 1)}^{2}  - 2( - 1) - 3 = 2 + 1 - 3 = 0 \\  \\ p(2) =  {2}^{2}  - 2(2) - 3 = 4 - 4 - 3 =  - 3 \\  \\ now \\  \\ p(3) + p( - 1) + p(2) =  - 3 \\  \\

Hope it Helps

Answer:

-3

Step-by-step explanation:

p(x)=x2−2x−3

putting value

  • p(3)=32−2(3)−3=9−6−3=0
  • p(−1)=(−1)2−2(−1)−3=2+1−3=0
  • p(2)=22−2(2)−3=4−4−3=-3

So,

  • p(3)+p(−1)+p(2)=−3

hope you have got your answer....
