Answer:

Given polynomial equation x2+x-p (p+1)

x2+x-p(p+1)=0

On factorising we get,

x2+(p+1)x-px-p(p+1)=0

x(x+p+1) -p(x+p+1)=0

(x+p+1)(x-p)=0

x=-p-1, and x= p

The zeros of polynomial are: p-1 and p

explanation

x2 +x−p(p+1)=0

x2 +x−p(p+1)=0⇒x2+(p+1)x−px−p(p+1)=0

x2 +x−p(p+1)=0⇒x2+(p+1)x−px−p(p+1)=0⇒x(x+(p+1))−p(x+(p+1))=0

x2 +x−p(p+1)=0⇒x2+(p+1)x−px−p(p+1)=0⇒x(x+(p+1))−p(x+(p+1))=0⇒(x−p)(x+(p+1))=0

make me brainliest and give me a heart or thanks

⇒x−p=0 OR x+(p+1)=0

⇒x−p=0 OR x+(p+1)=0⇒x=p OR x=−(p+1)
