Question

Multiply in column method
(3m-6m) and (4m+3n)​

Answer 1

Answer:

$(3m - 6m)(4m + 3n) \\ = 12 {m}^{2} + 9mn - 24 {m}^{2} - 18mn \\ = - 12 {m}^{2} - 9mn \\ = - 3m(4m + 3n)$

Answer 2

Answer:

-- { 3m ( 4m + 3n )} - { 6m ( 4m + 3n )}

-- { 3m x 4m + 3m x 3n } - { 6m x 4m + 6m x 3n }

-- ( 12m^2 + 9mn ) - ( 24m ^2 + 18mn )

-- 12m^2 - 24m^2 + 9mn + 18mn

Or

--- 3m ( 4m + 3n ) - 6m ( 4m + 3n )

---- ( 3m - 6m ) ( 4m + 3n )
