Question

(a+b-c)(a-b-c) multiply​

Answer 1

Answer:

$= > (a + b - c)(a - b - c) \\ = > (a - c + b)(a - c - b) \\ = > {(a - c)}^{2} - {b}^{2} \\ = > {a}^{2} - 2ac + {c}^{2} - {b}^{2} .$

Answer 2

(a + b - c) (a - b - c)

________ [ GIVEN ]

• We have to multiply it.

____________________________

→ (a + b - c) (a - b - c)

→ a(a - b - c) +b(a - b - c) -c(a - b - c)

→ a² - ab - ac + ab - b² - bc - ac + bc + c²

→ a² - b² + c² - ab + ab - bc + bc - ac - ac

→ a² - b² + c² - 2ac

___________________________

a² - b² + c² - 2ac
