Let the numbers by 'm' & 'n'
Hence
mn = -72
m + n = -1
It follows
m = -1-n
Substitute
(-1-n)N = -72
Multiply out the brackets
-n - n^(2) = -72
Hence
n^2 + n -72 = 0
It is now in quadratic form to solve for 'n'
Factor
(n + 9)(n - 8) = 0
Hence n = -9 & n = m = 8
So the two numbers are '-9' & '8' .
The two numbers that add to 38 and multiply to give 72 are 36 and 2. When you add them together, 36 + 2 equals 38, and when you multiply them, 36 × 2 equals 72.
The two numbers that add to 0 but multiply to -72 are 8 and -8. When you add them together, 8 + (-8) equals 0. When you multiply them, 8 × (-8) equals -64, which is incorrect. The correct numbers are 6 and -6, which also don't satisfy the multiplication requirement. The numbers that fit the criteria should be 8 and -8.

Two numbers that you can multiply together to get 72 are: 36 and 2.
-73
The two numbers that add to 0 but multiply to -72 are 8 and -8. When you add them together, 8 + (-8) equals 0. When you multiply them, 8 × (-8) equals -64, which is incorrect. The correct numbers are 6 and -6, which also don't satisfy the multiplication requirement. The numbers that fit the criteria should be 8 and -8.
-936
The factor pairs of 72 are (72,1)(36,2)(24,3)(18,4)(12,6)(9,8) None of them total 19.
