Answer 1

Materi : Bentuk dan Persamaan kuadrat

2x² - 6x + 5 = 0

[ Metode Rumus ABC / Kuadratik ]

{ a = 2 , b = -6 , c = 5 }

\________________/

x = ( b ± √[ b² - 4ac ] )/2a

x = ( -6 ± √[ {-6}² - 4{2}{5} ] )/2(2)

x = ( -6 ± √[ 36 - 40 ] )/4

x = ( -6 ± √[ -4 ] )/4

x = ( -6 ± [-1][2] )/4

Himpunan Penyelesaian :

x = ½( - i - 3 )

x = ½( i - 3 )

Semoga bisa membantu
