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)

To solve the math problem 14 x 26, you multiply the number 14 by 26 as follows. First, multiply 14 by 6, the last number of 26. That gives you 84. Then multiply 14 by 2, which gives you 28. Since this answer goes in the tens column, rather than the units column, however, you need to add a zero, giving you 280. Then you add 84 and 280, which gives you 364, which is your answer.
