Let the numbers be 'm' & 'n'
Hence
mn = 8
m + n = -6
m = 8/n
Substitute
8/n + n = -6
Multiply through by 'n'
8 + n^(2) = -6n
n^(2) + 6n + 8 = 0
Factor
(n + 4 )(n + 2) = 0
Hence n = -4 & n = -2
what two factors of -21 add up to -6
The two numbers that add to 2 and multiply to -48 are 8 and -6. When you add them together, 8 + (-6) equals 2. When you multiply them, 8 × (-6) equals -48.
