Question

Add the following ( 3xy + 2x -4 ) +(-4xy + 6x - 6)​

Answer 1

Answer:

3xy(2x+4y)

(3xy×2)+(3xy×4y)

6x²y+12xy²

here is.your.hint ans

Answer 2

${ \sf \mapsto \: ( 3xy + 2x -4 ) +(-4xy + 6x - 6)}$

${ \sf \mapsto \: 3xy + 2x -4 -4xy + 6x - 6}$

${ \sf \mapsto \: 3xy - 4xy + 2x + 6x -4 - 6}$

${ \sf \mapsto \: - xy + 8x - 10}$

${ \sf \mapsto \: 8x - xy - 10}$
