Question

1.What should be added to 9y^2-3xy to get 5xy+2 Step by step answer
PLZZZ HELP!!

Answer 1

Answer:

Let us assume the number which should be added as 'a'

9$y^{2}$ - 3xy + a = 5xy + 2

9$y^{2}$ + a = 5xy + 2 + 3xy

9$y^{2}$ + a = 8xy + 2

a = 8xy + 2 - 9$y^{2}$

Therefore, a = 8xy + 2 - 9$y^{2}$
