\(\left|\begin{array}{ccc} 2 x-4 & 4 & 0 \\ 2 & x-1 & 1 \\ 2 & 2 & 0 \end{array}\right|=0\)
భావన:
నిర్ణాయక విస్తరణ భావనను ఉపయోగించండి.
లెక్కింపు:
\(\left|\begin{array}{ccc} 2 x-4 & 4 & 0 \\ 2 & x-1 & 1 \\ 2 & 2 & 0 \end{array}\right|=0\)
మూడవ నిలువు వరుసకు సంబంధించి విస్తరించండి, అప్పుడు మనకు లభిస్తుంది
\(\rm 0-1((2x-4)\times(2)-2\times4)+0=0\)
⇒ 4x - 8 - 8 = 0
⇒ 4x = 16
⇒ x = 4
కాబట్టి ఎంపిక (1) సరైనది.
