Question

find the sum of the following expression Xy- 4x. + 2y2​

Answer 1

Step-by-step explanation:

Adding the given terms, we have

(i) 7abc + (- 5abc) + (9 abc) + (- 8abc)

= 7abc - 5abc + 9abc - 8abc

= (7 - 5 + 9 - 8)abc

= (16 - 13)abc

= 3abc

(ii) 2x2y + (- 4x2y) + 6x2y + (- 5x2y)

= 2x2y - 4x2y + 6x2y - 5x2y

= (2 - 4 + 6 - 5)x2y

= (8 - 9)x2y

= -x2y
