Find two numbers whose sum is 19 and the product is 48


y=19-x

xy=48
x(19-x)=48
19x-x² = 48
-x²+19x-48 = 0

a=-1, b=19, c=-48











Using the +







, 



      
So 3+16 = 19,  3*16 = 48

Using the -







, 



      
So 16+3 = 19,  16*3 = 48

Not really a different answer, just swapping the letters.

Answer: 3 and 16
