Answer:the roots are -( p) and (-1-p)
Step-by-step explanation:
X^2+x-p(p+1) = 0
Here it is in the form of ax^2+ bx+c = 0
=>a=1,b=1 ,c=-p^2-p
D = b^2 - 4ac
= 1-4×1×(-p2 - p)
= 1+4p^2+4p
Now, alpha = - b + root D / 2a
= -1 + 2p + 1 /2
= 2p / 2=p
and beta = -b - root D / 2a
= -1 -2p - 1 /2
= -2 - 2p /2
= -2 (1 + p) / 2
= -1 - p
Therefore the roots are - ( p) and (-1 - p)
