the two numbers are 3 and - 4
Step-by-step explanation:
Product: xy = - 12, or x = - 12/y
Sum: x + y = - 1, or - 12/y + y = - 1
Let's multiply all three terms by y to eliminate the fractional terms:
-12 + y^2 = - y, or
y^2 + y - 12 = 0
This factors into (y + 4) (y - 3) = 0, yielding y = - 4 and y = 3.
Earlier we found that x = - 12/y. Here, if we choose y = - 4, x = - 12 / (-4) = 3
and so the two numbers are 3 and - 4. Note that 3 (-4) = - 12, as required, and that 3 - 4 = - 1, also as required.
