Thanks, I remembered now.shaon0 said:USE THESE AND MANIPULATE:
Sum of roots: a+b+c =2
Product of roots: abc = 1/2
Sum of roots (twice) ab+ac+bc =3/2
NOTE: (use simultaneous equations)
Yeayh no worries but is this 4unit. Does it have complex numbers that polynomial?jchoi said:Thanks, I remembered now.
b+c = 2-a
c+a = 2-b
etc... thanks
btw @ kaz1-
using this way, you don't have to bother expanding, and it's much easier.
