Question

Subtract x² - 5xy +2 from 2x² + 5xy + 5​

Answer 1

⇢ 2x² + 5xy + 5 - (x² - 5xy +2)

⇢ 2x² + 5xy + 5 - x² + 5xy - 2

⇢ x² + 10xy + 3

Answer 2

Answer:

Subtract x² - 5xy +2 from 2x² + 5xy + 5​ then we get x² + 10xy   +3.

Step-by-step explanation:

Subtract x² - 5xy +2 from 2x² + 5xy + 5​

Vertical method

   2x² + 5xy + 5​

-     x² - 5xy   +2

________________

      x² + 10xy   +3

Horizontal method

(2x² + 5xy + 5​) - (x² - 5xy +2)

=  2x² + 5xy + 5​  -  x² +5xy -2

Rearrange similar term

=  2x²   -  x² + 5xy  +5xy + 5​ -2

= x² + 10xy   +3
