Step 1: Draw a line with a point which divides x,y
Step 2: Total distance of this line =x+y
Step 3: Now we have to find out the square of x+y i.e., Area of square = (x+y)
Step 4: From the diagram, inside square red and yellow be written as x
,y
Step 5: The remaining corner side will be calculated as rectangular side = length × breadth = x×y
Therefore, Area of the big square = Sum of the inside square +2 times the corner rectangular side
(x+y)
Hence, geometrically we proved the identity (x+y)
+2xy.
Step-by-step explanation:
This is how (x+y)^2 = (x+y)*(x+y) = x(x+y) +y(x+y) = x^2 + xy + xy + y^2 = x^2 + y^2 + 2xy
