The real solution of the equation (2 + I) x square minus (5 + I) x plus (2 minus 2I) = 0 is

The real solution of the equation (2 + I) x square minus (5 + I) x plus (2 minus 2I) = 0 is

(2+i)x²-(5+i)x+(2-2i)=0
X is a real number
2x²+x²i-5x-xi+2-2i=0
(2x²-5x+2)+(x²-x-2)i=0
Then 2x & sup2; - 5x + 2 = 0 and X & sup2; - X-2 = 0 hold simultaneously
(2x-1)(x-2)=0
(x-2)(x+1)=0
The common root is x = 2
So the real solution is x = 2
