Question

If the sum of two algebraic expression is 4x² + 4xy - y2 and one of them is x² + 2xy then, find the other​

Answer 1

Answer:

6xy-y2-x²

Step-by-step explanation:

let the other expression be=x

x²+2xy + x=4xy -y2

x=4xy - y2-x²+2xy

x=4xy+2xy-y2-x² [Adding Like Terms]

x=6xy-y2-x²

so the other expression is 6xy-y2-x²
