we Know,
a² - b² = (a - b)(a + b) use this identity .
C² - (x + y)²
= {C - (x + y) }{C + (x + y)}
=(C - x - y)(C + x + y)
a² - b² = (a - b)(a + b) use this identity .
C² - (x + y)²
= {C - (x + y) }{C + (x + y)}
=(C - x - y)(C + x + y)

C²-(x-y)²solve using Identity.
→ C²-(x-y)²
[ Use identity - a²-b² = (a+b)(a-b)]
→ {C-(x-y)}{c+(x-y)}
→ (C-x+y)(C+x-y)
===================================
→ C²-(x-y)²
[ Use identity - a²-b² = (a+b)(a-b)]
→ {C-(x-y)}{c+(x-y)}
→ (C-x+y)(C+x-y)
===================================
