Please help regarding the question​

Answer 1

Answer:

hii

Step-by-step explanation:

f(x)=x^2-px+70

here a=1,b=p,c=70

let a and b are the zeroes of f(x)

A^2+B^2 =149

(A+B)^2 - 2AB=149

(-b/a)^2-(2c/a)=149

(-(-p/1)^2 - 2 (70/1)=149

(P)^2 - 140=149

P^2=149+140

P^2=289

P=17.

plz mark as brainlist.

hope this help u.
