⎝⎛X+2y+3z4y+5z6z⎠⎞ =x⎝⎛100⎠⎞+y⎝⎛240⎠⎞+z⎝⎛356⎠⎞
Transforming matrix
A=⎝⎛100240356⎠⎞
Characteristic equation of A is
∣∣A−Iλ∣∣=∣∣1−λ0024−λ0356−λ∣∣=0
Expanding
(1−λ)[(4−λ)(6−λ)−0]+2(0)+3(0)=0
⟹(1−λ)(4−λ)(6−λ)=0
The distincts roots of A are also roots of the minimum polynomial g(x)
∴g(x)=(x−1)(x−4)(x−6)
