Question

What should be subtracted from x²+y² to obtain 2x² +3xy​

Answer 1

Answer:

x² + y² + 3xy should be subtracted from x² + y² to obtain 2x² + 3xy​.

Step-by-step explanation:

Given:

1st Term = x²+y²

2nd Term = 2x² + 3xy​

Asked:

1st Term - ? = 2nd Term

Solution:

Let the number subtracted from x² + y² be '⊕',

Equation formed:

x² + y² - ⊕ = 2x² + 3xy​

- ⊕ = x² + y² - 2x² + 3xy​

- ⊕ = - x² + y² + 3xy

- ⊕ × (- 1) = - x² + y² + 3xy × (- 1)

⊕ = x² + y² + 3xy

Therefore, x² + y² + 3xy should be subtracted from x²+y² to obtain 2x² +3xy​.
