Answer 1

Answer:

I got a similar answer from Toppr. Hope it will help and no need to thanks me or marking this answer as the brainliest as I haven't did this of my own!

Answer 2

Answer: P + Q + R = 0

Step-by-step explanation:

Polynomial : $Px^2 + Qx + R$

Zeroes : x = 1 , x = -2

To find : P + Q + R

P(1)² + Q(1) + R = 0

P + Q + R = 0
