Answer:

a²-b²+2bc-c² =a² - (b² -2bc +c²)

a²-b²+2bc-c² =a² - (b² -2bc +c²)                    =a² - (b-c)²

a²-b²+2bc-c² =a² - (b² -2bc +c²)                    =a² - (b-c)²                    =(a-(b-c))(a+(b-c))  [ using identity a²-b² =(a-b)(a+b) ]

a²-b²+2bc-c² =a² - (b² -2bc +c²)                    =a² - (b-c)²                    =(a-(b-c))(a+(b-c))  [ using identity a²-b² =(a-b)(a+b) ] 

a²-b²+2bc-c² =a² - (b² -2bc +c²)                    =a² - (b-c)²                    =(a-(b-c))(a+(b-c))  [ using identity a²-b² =(a-b)(a+b) ]                    = (a-b+c)(a+b-c)

a²-b²+2bc-c² =a² - (b² -2bc +c²)                    =a² - (b-c)²                    =(a-(b-c))(a+(b-c))  [ using identity a²-b² =(a-b)(a+b) ]                    = (a-b+c)(a+b-c)hence.,a²-b²+2bc - c²  = (a-b+c)(a+b-c)
