The value of two numbers are, 12 and - 36
We have to give that,
Multiplication of two numbers = - 144
And, Add two numbers = - 24
Let us assume that,
Two numbers are x and y.
Hence,
xy = - 144 .. (i)
x + y = - 24
x = - 24 - y .. (ii)
From (i),
y (- 24 - y) =- 144
- 24y + y² = -144
y² - 24y + 144 = 0
y² - 12y - 12y + 144 = 0
y (y - 12) - 12 (y - 12) = 0
(y - 12) (y - 12) = 0
y = 12
From (ii),
x + y = - 24
x + 12 = - 24
x = - 24 - 12
x = - 36
Hence, Two numbers are, 12 and - 36

Answer:
Option A.
Step-by-step explanation:
The given equations are
...(1)
...(2)
From equation (1), we get
...(3)
Substitute in equation (2).
Put x=0, in equation (3).
Put x=-6, in equation (3).
It means, (0,6) and (-6,0) are two solutions of the given system of equations.
Therefore, the correct option is A.
