The equation x+5x+m = 0 about x has two imaginary roots x 1 and x2, which satisfies
X+5x+m = 0 transformed (x+5/2) = 25/4-m.

X= Add 5/2 under the root sign (25/4-m).

Or add 5/2(25/4-m) under the minus sign (sorry, I can't type with good symbols).

Ix 1-x2I=2*(25/4-m)=3 Solve the equation m=4.

Typing takes a long time, I hope I can help you!
