Let the numbers be 'm' & 'n'
Hence
m + n = 2
mn = - 280
It follows that m = 2 - n
Substitute
(2 - n)n = -280
Multiply out the brackets
2n - n^2 = -280
n^2 - 2n - 280 = 0
It is now in Quadratic form. Either use the Quadratic Eq'n or 'Complete the Square'.
n^2 - 2n = 280
(n - 1)^2 - (-1)^2 = 280
(n - 1)^2 = 281
Square root both sides
n -1= sqrt(281)
n = 1 +/- sqrt(281)
-46
-5 and -8

If you multiply 4 by 58 and add 48, the answer is 280.
The two numbers that multiply to -72 and add to -29 are approximately 3.57 and -32.57.
The two numbers that multiply to get 35 and add to 2 are 7 and -5. When you multiply them (7 * -5), you get -35, and when you add them (7 + -5), you get 2. Thus, the numbers are 7 and -5.
The two numbers that multiply to -30 and add up to 13 are 15 and -2. When you multiply 15 and -2, you get -30, and when you add them together, you get 13.
The two numbers that add to give you 25 and multiply to give you 26 are 24 and 1. When you add 24 and 1, you get 25, and when you multiply them, you get 26.
