(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution

the usual method i.e. det(A - bI) = 0

i get the equation finally as b[3][/SUP] - 75b[2][/SUP] + 1850b -15576 = 0

from this i get b[1][/SUB][2][/SUP] + b[2][/SUB][2][/SUP] + b[3][/SUB][2][/SUP] = 1925 < 1949

is there an easier/more creative method??

forgot to add tags .. dont delete..
