1) 3х^2 - 14х + 8 = 3( x - 2/3 )( x - 4 ) = ( 3x - 2 )( x - 4 )
D = 196 - 96 = 100 = 10^2
X1 = ( 14 + 10 ) : 6 = 4
X2 = ( 14 - 10 ) : 6 = 2/3
2) ( x - 4 ) / ( ( 3x - 2 )( x - 4 )) = 1 / ( 3x - 2 )
Ответ ( 1 / ( 3х - 2 ) )

1) 3х^2 - 16х + 5 = 3( x - 1/3 )( x - 5 )) = ( 3x - 1 )( x - 5 )
D = 256 - 60 = 196 = 14^2
X1 = ( 16 + 14 ) : 6 = 5
X2 = ( 16 - 14 ) : 6 = 1/3
2) ( ( 3x - 1 )( x - 5 )) / ( x - 5 ) = 3x - 1
Ответ ( 3х - 1 )
