Question

what should be added to x² +xy+y² to get 2x + 3xy​

Answer 1

Step-by-step explanation:

We have to find the number which should be added to x² +xy+y² to get 2x + 3xy​ so,

(_______)+ x² +xy+y² = 2x+3xy

∴ (_______) = 2x+3xy - ( x² +xy+y²)

                    = 2x+3xy - x²-xy-y²

                    = 2x-x²+3xy-xy-y²

                    = 2x-x²+2xy-y² (Ans)
