Question

enrichment activity verification of the identity (a+b)²=a²+2ab+b²​

Answer:

Step-by-step explanation:

lhs

[a+b]^2

= a^2+b^2+2*a*b

= a^2+2ab+b^2

Answer 2

The identity (a+b)2 = a2 + 2ab + b2 is verified by cutting and pasting of paper. This identity can be verified geometrically by taking other values of a and b. Divide a square plot into four parts (quadrilaterals) such that two parts have same area and other two are squares
