factorize a^2-b^2-c^2-2bc+a+b-c
Answers
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)
