1) add- x^2,2x^2,-6x^2
2) add- 3x^2y^2-4xy+5 and 2x^2y^2 + 3xy-7
Answers
First Answer:-
Given:
- x²
- 2x²
- -6x²
What To Find:
The sum of the given expressions.
Solution:
(x²) + (2x²) + (-6x²)
Remove the brackets,
⇒ x² + 2x² - 6x²
Solve the like terms,
⇒ -3x²
Final Answer:
Thus, the sum of the expression is -3x².
Second Answer:
Given:
- 3x²
- y² - 4xy + 5
- 2x²
- 2y² + 3xy - 7
What To Find:
The sum of the given expressions.
Solution:
(3x²) + (y² - 4xy + 5) + (2x²) + (2y² + 3xy - 7)
Remove the brackets,
⇒ 3x² + y² - 4xy + 5 + 2x² + 2y² + 3xy - 7
Rearrange the like terms,
⇒ 3x² + 2x² + y² + 2y² - 4xy + 3xy + 5 - 7
Solve the like terms,
⇒ 5x² + 3y² - xy - 2
Final Answer:
Thus, the sum of the expression is 5x² + 3y² - xy - 2.
