Question

18. What should be subtracted from 6xy + x^2 - 4x + 8 to get 2x^2 + 5x - 8xy + 5 ?​

Answer 1

Answer:

-9x^2-x^2+14xy+3

Step-by-step explanation:

subtract second no. from first no.

Answer 2

Answer:

Let the number be a

Then,

xy+x^2- 4x +8 -a= 2x^2+5x-8xy+5

Take -a to right hand sideside. 2x^2 + 5x - 8xy + 5 to t hand side

xy+x^2- 4x +8 -2x^2- 5x+ 8xy- 5= a

9xy -x^2 -9x +3=a
