Materi : Bentuk dan Persamaan kuadrat
x² + x + 20 = 0
[ Metode Rumus ABC / Kuadratik ]
{ a = 1 , b = 1 , c = 20 }
x = ( b ± √[ b² - 4ac ] )/2a
x = ( 1 ± √[ 1² - 4(1)(20] )/2[1]
x = ( 1 ± √[ -1 . 79 ] )/2
Himpunan Penyelesaian :
x = ( 1 + i√79 )/2
x = ( 1 - i√79 )/2
Semoga bisa membantu
Rumus:
Rumus penyelesaian:
ax² + bx + c = 0
Diketahui:

b = 1
c = 20
Jawab:
" Life is not a problem to be solved but a reality to be experienced! "
