Thanks☺️☺️
​

Answer 1

Here is the answer:

49a^2+70ab+25b^2
= (7a)^2 + 2×7a×5b + (5b)^2
= (7a + 5b)^2

Using identity,
(a+b)^2 = a^2+2ab+b^2

hope this will help.

Answer 2

Answer:

We have

=49a^2 +70ab+25b^2

=(7a) ^2 +(5b)^2 +70ab

We know that a^2 +b^2 +2ab =(a+b) ^2

So,

=(7a+5b)^2

= (7a+5b)(7a+5b)

These are the factors of this,
