x squared minus 16x plus 65 = 0
x² - 16x + 65 = 0
delta = 256 - 260 = -4
x1= (16 - i2 )/2 = 8 - i
x2= 8 + i
(x - x1)(x - x2)=0
can you maybe explain to me how you got that in words? like the "8+i" part I don't understand
8 plus i : is a number complex on the set C .
if you don't know it just read the course about number complexe
