Factorise the following expression 121 square + 110 AB + 25 b square

Answer 1

I think there must be 121a square.

Then itz answer would be :-

(11a+5b)square which means=

(11a+5b)(11a+5b)

Answer 2

Answer:

(121)^2 + 110ab +(25)^2

according to this formula (a + b)^2=a^2 + b^2 +2ab)

a=(121)^2=11

b=(25)^2=5

(11+5)^2 = (11+5) (11+5)
