What two numbers have a sum of -3 and a product of -42?

Answer 1

39

Answer 2

Let's denote the two numbers as x and y. We know that x + y = -3 and x * y = -42. By solving the system of equations, we can find that the two numbers are -7 and 6. This is because -7 + 6 = -1 and -7 * 6 = -42.

Answer 3

x+y=-3

xy=-42

Isolate y in both equations:

y=x-3

y=-42/x

x-3=-42/x

x^2-3x=-42

x^2-3x+42=0

x=(3±√-157)/2

x is imaginary
