Question

Read the question in the picture .

Answer 1

(a^2)-49=(a^2)-(7^2)

So by using the formula:-

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

(a^2)-(7^2)=(a+7)(a-7)

[(a^2)-(7^2)]/(a+7)

[(a+7)(a-7)]/(a+7)

a-7

Hence 1st option is correct.

Answer 2

Answer:

a^2-49/a-7=a-7

Step-by-step explanation:

a^2-49/a-7

remains a^2-7/a as we know that 7^2=49

gives us a-7 as we reduce one a from a^2

Hope it helps...
