${7x}^{2} - \: 8xy \: + \: 3$

Step-by-step explanation:

hope it helps

Answer 2

Step-by-step explanation:

Let the no. be x .

ATQ,

9x²-5xy - x = 2x² +3xy-3

9x²-5xy -(2x²+3xy-3)=x

9x²-5xy-2x²-3xy+3=x

7x²-8xy+3 = x

Therefore,

7x²-8xy+3 should be subtracted from 9x²-5xy to get 2x² + 3xy - 3.
