1)4xy-7y+12x-2l​

Answer 1

Answer:

(4x - 7)(y + 3)

Step-by-step explanation:

4xy-7y+12x-21

4xy + 12x - 7y - 21

4x(y +3) -7(y + 3)

(4x - 7)(y + 3)

Answer 2

Answer:   (4x - 7)(y + 3)

Step-by-step explanation:  

4xy - 7y + 12x - 21

group them according to their variables and coefficients

4xy + 12x - 7y - 21

(4xy + 12x) - (7y - 21)

Take the GCF

4x(y +3) -7(y + 3)

(4x - 7)(y + 3)
