Question

3.) Factorize the expressions.

c. (a^2 - 2ab + b^2)-c^2​

Answer 1

Answer:

Using identity a2 + 2ab + b2 = (a + b)2

= (a + b)2 - c2

Using identity a2 - b2 = (a + b)(a - b)

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

∴ a2 + 2ab + b2 - c2 = (a + b + c)(a + b - c)

hope it helps you

Answer 2

Answer:

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

Step-by-step explanation:

(a^2-2ab+b^2)-c^2

(a-b)^2-c2

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