Answer:
-2, 3
Step-by-step explanation:
yeah that's it I don't have any explanation or formula
let the numbers be x and y
xy = -6
x + y = 1
from x + y = 1
y = 1 - x
x(1 - x) = -6
x - x² + 6 = 0
-x² + x + 6 = 0
on solving,
x = -2 or x = 3
y = 1 - (-2) = 3
y = 1 - 3 = -2
x1 = -2, y1 = 3.
x2 = 3, y2 = -2.
