Answer:
x^2-14x +48
Step-by-step explanation:
First we'll simplify the equation yo get the value of alpha and beta .
p(x)=0 = x^2-5x+6
x^2-3x-2x+6=0
x(x+-3)-2(x-3)=0
(x-2)(x-3)=0
x-2=0,x-3=0
alpha = x=2,beta=x=3
now zeroes of second polynomial
=2×2+2
=6
and
2×3+2=8
the required polynomial=
k(x^2-(alpha+beta)x +alpha×beta)
=k(x^2-(6+8)x +6×8)
when k=1,
x^2-14x+48
