Answer:

Mark me as brainlist

Step-by-step explanation:

=>3xy(4x-5y)+3x²y

=>12x²y-15xy²+3x²y

=>15x²y-15xy²

=>15xy(x-y)

Answer 2

$\huge{ \bold{ \underline {\underline{Given:}}}}$

3xy(4x-5y)+3x^2y

$\pink{ \bold{ \underline {\underline{Step \: by \: step \: explanation :}}}}$

$\bold{ = 3xy(4x - 5y) + 3 {x}^{2} y } \\ \bold{= 12 {x}^{2} y - 15x {y}^{2} + 3 {x}^{2} y }\\ \bold{= 15 {x}^{2} y - 15x {y}^{2}} \\ \huge{ = 15xy(x - y)}$
