Question 440838
Let x, y be the two numbers.
Given:
x + y = -17
x*y = 66
From the 2nd equation, y = 66/x
Substitute this value for y in the 1st equation:
x + 66/x = -17
Multiply through by x:
x^2 + 66 = -17x -> x^2 + 17x + 66 = 0
Solve for x using the quadratic formula:
x = (-17 +- sqrt(17^2 - 264))/2 -> x = (-17 +- 5)/2
This gives x = -11, -6
Which means y = -6, -11
So the two numbers are: -6, -11
