 \huge \bold{ \mathfrak{ answer}}

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)

Step-by-step explanation:

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)
