please it is very very urgent I will mark as brainliest​

Answer 1

Here is ur answer

PLEASE MARK ME BRAINLIST

Answer 2

Given:

Five expressions:

• First expressions :- 2x² + 3xy
• Second expressions :- -xy - y²
• Third expressions :- 3x - y²
• Fourth expressions :- x²
• Fifth expressions :- -x² + xy + y²

What To Find:

We have to find,

• Sum of 1st and 2nd expressions
• Sum of 3rd, 4th and 5th expressions
• Difference of 1st-2nd and 3rd-4th-5th expressions

Solution:

• Finding the sum of 1st-2nd expressions.

(2x² + 3xy) + (-xy  - y²)

Remove the brackets,

⇒ 2x² + 3xy - xy - y²

Rearrange the like terms,

⇒ 2x² - y² + 3xy - xy

Solve the like terms,

⇒ 2x² - y² + 2xy

• Finding the sum of 3rd-4th-5th expressions.

(3x - y²) + (-x²) + (-x² + xy + y²)

Remove the brackets,

⇒ 3x - y² - x² - x² + xy + y²

Rearrange the like terms,

⇒ - x² - x² - y² + y² + 3x + xy

Solve the like terms,

⇒ -2x² + 3x + xy

• Finding the difference.

(2x² - y² + 2xy) - (-2x² + 3x + xy)

Remove the brackets,

⇒ 2x² - y² + 2xy + 2x² - 3x - xy

Rearrange the like terms,

⇒ 2x² + 2x² - y² + 2xy - xy - 3x

Solve the like terms,

⇒ 4x²  - y² + xy - 3x

∴ Thus, the difference is 4x²  - y² + xy - 3x.
