Question

a^2+b^2-c^2-2ab factories the equation ​

Answer 1

Answer:

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

Step-by-step explanation:

a²+b²-c²-2ab

= (a²-2ab+b²) - c²

= (a-b)²-c²

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

Answer 2

Step-by-step explanation:

$a {}^{2} + {b}^{2} - 2ab - {c}^{2} \\ (a - b) {}^{2} - c ^{2} \\ (a - b - c)(a - b + c)$

applying the identities-

(a-b)²=a²+b²-2ab

a²-b²=(a-b)(a+b)
