Given:
Two expressions
- 3xy - 2yz + 3zx
- 3yz - 2xy + 2zx
What To Do:
We have to find the sum of the above expressions.
Solution:
(3xy - 2yz + 3zx) + (3yz - 2xy + 2zx)
Remove the brackets,
⇒ 3xy - 2yz + 3zx + 3yz - 2xy + 2zx
Rearrange the like terms,
⇒ 3xy - 2xy - 2yz + 3yz + 3zx + 2zx
Solve the first like term,
⇒ xy - 2yz + 3yz + 3zx + 2zx
Solve the second term,
⇒ xy + yz + 3zx + 2zx
Solve the third term,
⇒ xy + yz + 5zx
∴ Therefore, the sum of the expressions is xy + yz + 5zx.
