Question

if two zeros of the polynomial X square + 9 x minus 5 are alpha and beta then find the value of Alpha square plus beta square​

Answer 1

Step-by-step explanation:

p(x)2x²+3x-6

sum of zereos=-b/a

alpha+beta=-3/2

product of zereos=c/a

alpha*beta=-6/2=3

A.T.Q

(alpha)²+(beta)

(alpha+beta)²-2alpha*beta

by putting value

(-3/2)²+2*3

9/4+6

taking lcm

answer is 99/12
