Explain the polynomial geometrically: (6x+5)2=36x2+52+60x

Open in App
Solution

Step 1: Draw a line with a point which divides 6x,5
Step 2: Total distance of this line =6x+5
Step 3: Now we have to find out the square of 6x+5 i.e., Area of big square, ABCD= (6x+5)2
Step 4: From the diagram, inside square red and yellow square, be written as 36x2,52
Step 5: The remaining corner side will be calculated as rectangular side = length × breadth = 6x×5
Therefore, Area of the big square, ABCD= Sum of the inside square + 2 times the corner rectangular side.
(6x+5)2=36x2+52+60x
Hence, geometrically we proved the identity (6x+5)2=36x2+52+60x.
