How do you solve (5a+3)2-10a2-6a? Which method is used for this?
If you mean solve : (5a+3)^2 - 10a^2 - 6a = 0 ; then: 25a^2 + 30a + 9 - 10a^2 - 6a = 0 15a^2 + 24a + 9 = 0 Now solve for x using the quadratic formula.; you'll get 2 solutions.
Ok... but in a(3+b)-a+b does the coefficient of a in the first term affect whether it is a complex trinomial or not, or does it depend on what numbers are in the brackets?

What are you asking? a(3 + b) - a + b = 2a + 4b , that's it.
