Answer 1

Answer:

plz mark me as brainliest

Step-by-step explanation:

let the number be M

x^3+3x^2y+3xy^2+y^3+M=x^3+y^3

M=(x^  3 +y  ^3  )−(x  ^3  +3x  ^2  y+3xy  ^2  +y  ^3 )

M=x  ^3  +y  ^3 −x  ^3  −3x  ^2  y−3xy  ^2 −y  ^3

Collecting like terms,

M=x  3  −x ^ 3 +y^  3 −y ^ 3 −3x  ^2  y−3xy  ^2

M=−3x  ^2  y−3xy  ^2
