Answer:
The easiest way is to use the following quadratic equation related to sum and product:
X² - SX + P =0, where S = sum and P = product
X² - (-24)X + 144 = 0
X² + 24X + 144 = 0.
Extract the roots: X' = [-b+√(b²-4ac)]/2a and X" = [-b-√(b²-4ac)]/2a
X' = [-24+√(-24)²-4(1)(144)]/2 X' = (-24√0)/2 → X' = X" = -12
Then the 2 numbers are -12 and -12
Put your values in this method you will get the answer
