Question

calculate the distance between (2+2i) and (6+5i)

Answer 1

Answer:

Answer is 24.3

Step-by-step explanation:

2(6+5i)+2i(6+5i)

12+10i+12i+10i^2

10i^2+22i+12

use formula of quadric equation

that is X=b+√b^2-4ac/2a

here a=10,b=22,c=12

i = 484+√484-480/20

i = 484+√4/20

i = 484+2/20

i= 486/20

i =24.3

hence distance = 24.3
