Helo me solve this problem with the quadratic equation pls

x^2-8x+4

Please provide step by step instructions please

use quadratic formula

x= (-b± √▲)/2a

√▲ = √(b²-4ac)
= √(8² -4*1*4) =√ ( 64 -16) =√48

x= (8± √48)/2 = 4 ± √(48)/2
√48= √ (16*3) = 4√3
x= 4± 2√3

x^2-8x+4
(8±√64-16)/2
(8±4√3)/2
(4±2√3)
