Question

What should be taken away from 4x - 3y2 + xy -10 to obtain - - y - 2xy +10
​

Answer 1

Answer:

4x - 3y²+ 3xy -20

Step-by-step explanation:

Let Q be subtracted from 4x- 3y²+xy -10 to obtain - y- 2xy+10 .

4x- 3y²+xy -10 - Q = - y - 2xy +10

➜ Q= 4x- 3y²+xy -10 + y + 2xy -10

➜Q = 4x - 3y²+ 3xy -20
