product = -p(p+1)
sum = -1
thus roots can be simply taken out as
p and -(p+1) becuase these satisfy the criteria.
similarly you can take out the roots of second question which are
m and -(m+3)
or do it this way
let the roots be a and b
thus a*b = -p(p+1)
a+b=-1
a=-1-b
therfore
b(-1-b) =-p(p+1)
-b(1+b) = -p(p+1)
thus b =p
and a =-(1+p).

MilitheQUORAN:
can - (x+1) be its root too??
x is a variable you need to find the x...
-(x+1) as a root of a polynomial in x doesn't makes any sense
okh! Thank you
