Which two numbers will add up to 2 and when multiply gives us -280?
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)
