Some plusses and/or minuses would have assisted. (2x - 5)(x + 6) are factors of 2x2 + 7x - 30, giving solutions for x of 2.5 and -6; (2x + 5)(x - 6) are factors of 2x2 - 7x - 30, giving solutions of -2.5 and 6.
Yes. In fact, you can have any number of solutions you want. Here is an example of an algebraic equation with three solutions:(x - 2)(x - 5)(x + 4) = 0 The solutions are 2, 5, 4, since for each of these, one of the factors will be zero, and therefore, the product will also be zero.
Factors (x - 7)(x + 2) so x = 7 or -2.
Completing the square will work when the solutions are irrational. Finding irrational factors is extremely difficult.
1,2,4,7,14,28. These are only the whole number factors. Of course, there are an infinite number of solutions to this because all that is required it that xy=28. If x and y are unrestricted, and their domain is all real numbers, there are infinite solutions.
There are many problems involving factors and the question needs to be more specific.

There is no way to predict that. It will depend on a number of factors, including which candidate runs the most effective campaign and offers the best solutions to the nation's problems.
These factors are:- homogeneity of the solution- dimension of particles
Concentration of aqueous solutions. Temperature of aqueous solutions. Electrode surface area.
