Question

a=b=1,a square-b square =a square -a×b sol this sum gives ans like 0=0,2=2​

Answer 1

Answer:

a=B=1.... then ans is 2=2

Answer 2

Answer:

a=b=1

a=1, b=1

a²-b²=a²-a.b

(1)² - (1)² = (1)²-1.1

1 - 1 = 1 - 1

0 = 0 (prove)

or,

a² - b² = a² - ab

a² + ab = a² + b²

(1)² + 1.1 = (1)² + (1)²

1 + 1 = 1 + 1

2 = 2 (prove)
