Question

Very easy math question.only answer 5th question. First to answer correctly will be marked as the brainliest .

Answer 1

Answer:

(a-b)

Step-by-step explanation:

(a^2-b^2) is (a+b)(a-b) as per the identity

therefore

(a^2-b^2)/(a+b)

(a+b)(a-b)/(a+b)

(a+b) gets cut

therefore

(a-b)

Answer 2

Answer:

(a - b)

Step-by-step explanation:

When factorized,

($a^{2} -b^{2}$) = (a + b) (a - b)

So,

($a^{2} -b^{2}$) / (a + b) = (a - b)
