x^2 = 12x + 5 tentukan akar akar dengan melengkapkan kuadrat sempurna

x² - 12x = 5
(x - 6)² - 36 = 5
(x - 6)² = 36 + 5
x - 6 = √41
x = 6 ± √41
x1 = 6 + √41
x2 = 6 - √41

x^2 = 12x +5
x^2 - 12x = 5
( x - 6)^2 - (6)^2 = 5
( x - 6)^2 - 36 = 5
( x - 6)^2 = 5+36
( x - 6)^2 = 41
( x - 6) = plus dan minus akar 41
