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

Good luck

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
