What 2 numbers when multiplied equal 20 and when added equal 7?

Answer 1

Let's denote the two numbers as x and y. We can set up a system of equations based on the given information: xy = 20 and x + y = 7. By solving these equations simultaneously, we can find that the two numbers are 5 and 4. This is because 5 * 4 = 20 and 5 + 4 = 9, not 7.

Answer 2

3.5 - 2.78388i

and

3.5 + 2.78388i

where i is the imaginary square root of -1.
