Question

factorise the following using suitable identities (a+b)²-c²​

Answer 1

Answer:

property: x² - y² = (x + y)(x - y)

In this case, x = (a - b) and y = c:

(a-b)^2-c^2

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

Answer 2

Answer:

(a+b+c) (a+b-c) apply formula a square plus b square equlas to a minus b into a plus b
