It is a similar problem of having a rectangle of area 30 units and the semi-perimeter is 10.3.
Using calculus, we find that the minimum real semi-perimeter is 2√30=10.95.
Unless you are working with complex numbers, there is a good chance that there is erroneous data in the question. Did you derive the data (like 10.3) from an experiment, or was it calculated from some other sources?
x.y=30 and x+y=10.3, I end up with
x=(21.83+60.66i)/(-5.15-5.89i).
i is the square root of (-1).
could you please show me how this equation will = 10.3
I am having problem to figure it out.
thank you.

my Teacher gave this problem
Ask the teacher if he/she expects complex roots, which are approx. 5.15±1.86i.
if my teacher expects complex roots, what will be the final answer if i add x+y = 10.3 = ??
thank you
thank you
If
x=5.15+1.86i
y=5.15-1.86i
xy=29.98
x+y=10.3
Note that numerical values are rounded (except 5.15).
Do the multiplication as an exercise.
