                                        6a(b-2)-3(b-2)

Answer 1

`56abc^2-8ac=8ac(7bc-1)`

`6a(b-2)-3(b-2)=(b-2)(6a-3)`

Answer 2

Answer 3

a) Ta có: \(56abc^2-8ac\)

\(=8ac\left(7bc-1\right)\)

b) Ta có: \(6a\left(b-2\right)-3\left(b-2\right)\)

\(=\left(b-2\right)\left(6a-3\right)\)

\(=3\left(2a-1\right)\left(b-2\right)\)
