(x-y)^2 +4xy = (x+y)^2
FOIL
x^2 -2xy+y^2 +4xy = (x+y)^2 x^2 -2xy
Combine like terms
x^2 +2xy +y^2 = (x+y)^2 x^2 +2xy
Factor
(x+y)^2 = (x+y)^2 (x+y)^2
I do not understand what you want me to solve.
Answer:
A line is a simple geometric shape that extends in both the directions, but a line segment has two defined endpoints. Both the figures are also different from a ray, as a ray has only one endpoint and extend infinitely in one direction.
