Let the numbers be 'm' & 'n'
Hence
mn = 51 (Multiplication)
m + n = -16 (Addition)
Algebraically rearrange
m = -16 -n
Ssubstitute
(-16-n) n = 51
-16n - n^2 = 51
n^(2) + 16n + 51 = 0 ( It is now in Quadratic form to solve).
Complete the Square
(n + 8)^2 - 8^(2) = -51
(n + 8)^2 = -51 + 64 = 13
Square root both sides
n + 8 = +/-sqrt(13)
n + 8 = +/- 3.60555....
n = -13.60555.... & -4.39444.... Are the two number.
