x²-(3√2+2i)x+6√2i=0

here , a = 1 ,b= - ( 3√2+2i) ,c= (6+√2i)

substitute these values in equation b²-4ac

we get,

- (3√2+2i)²-4×(1)×(6+√2i)

[ -(3√2)²- (2i)²+2× (-3√2)×(-2i) ] - [4 ( 6+√2i) ]

[18+4i²+12√2i] - [24+4√2i)

18 + 4i² + 12√2i - 24 - 4√2i

4i²+ 12√2i - 4√2i - 24 + 18

4i² + 8√2i - 6

so value of b²- 4ac from equation

x²- (3√2+2i)x+6√2=0 is 4i² + 8√2 - 6
