Answer:
- Over the real numbers there are no numbers to add to -2 and multiply to 3
- Over the complex set of numbers, the numbers that add to -2 and multiply to 3 are
Step-by-step explanation:
Let and be the numbers.
We know that they add to -2, so equation (1).
We know that they multiply to 3, so equation (2).
To find our numbers, let's solve our system of equations step-by-step:
Step 1. Solve for in equation (1):
equation (3)
Step 2. Replace equation (3) in equation (2) and solve for :
Using the quadratic formula with a=-1, b=-2, and c=-3 we get that
equation (4)
equation (5)
As you can see, the system of equation doesn't have a solution over the reals, but if you need a complex answer, let's keep on.
Step 4. Replace equations (4) and (5) in equation (3) and solve for :
- For
- For
The solutions of our system of equations are:
