Question

(a-b) whole square = (a+b) whole square - 4ab​

Answer 1

Answer:

we know that,

(a-b) whole square = a square + b square -2ab

and, (a+b) whole square = a Square +b square +2ab

case 1,

(a-b) whole square =(a+b) whole square -4ab

a square + b square -2ab = a square +b square + 2ab -4ab

then ,

a square + b square -2ab = a square +b square -2ab

so, they LHS = RHS
