Answer 1

Answer:

THIS IS YOUR ANSWER .

${a}^{2} - {b}^{2} + {c}^{2} + 2ab$

Answer 2

EXPLANATION.

⇒ (a + b - c)(a - b + c).

As we know that,

We can write equation as,

⇒ a x (a - b + c) + b x (a - b + c) - c x (a - b + c).

⇒ (a² - ab + ac) + (ab - b² + bc) - (ac - bc + c²).

⇒ a² - ab + ac + ab - b² + bc - ac + bc - c².

⇒ a² - b² - c² + 2bc.
