Negative numbers aren't in a solution set because in equations and inequalities you have to multiply and divide and a positive number divided by a negative number will be a negative number. Positive divided by positive will be positive. Negative divided by negative will be positive. So that's why negative numbers aren't a solution to any set or equation.

The square of a binomial is a pattern you would do well to remember.
.. (x +y)^2 = x^2 +2xy +y^2
Your expression has x^2 = 25a^2, so x = 5a. It also has y^2 = (b^2)/4, so y = b/2.
then the middle term is
.. 2xy = 2(5a)(b/2) = 5ab
The trinomial is
.. 25a^2 +5ab +(1/4)b^2 = (5a +b/2)^2
I think it’s b not 100% sure but I think
