Answer:
- 10
- 15ab
Step-by-step explanation:
1. The square of the binomial is ...
(* -2m)^2 = *^2 -4m* +4m^2

-4m* = -40
Both of these equations tell you the value of * is 10.

2. Same deal. Multiply ou the square and see what you have.
(3a +2.5b)^2 = 9a^2 +15ab +6.25b^2
The term missing on the right side of the given equation is 15ab.
