Answer:
x^2+3x+2
Step-by-step explanation:
u can see that the two zeroes alpha and beta .
their sum is given i.e alpha +beta = -3 and we know that aplha +beta =-B/a and alpha *beta is given as 2 and aplha *beta = c/a so when u put them in formula it will be like
alpha +beta=-3
-3/1=-b/a
which indicates b= 3
aplha * beta= 2
2/1=c/a
which indicates c=2
and in both cases a=1 so
the polynomial will be x^2+3x+2
hope it helps
