bantuin kak, pke cara yaa
Materi : Bentuk dan Persamaan kuadrat
x² - 5x + 6 = 0 { a = 1 , b = -5 , c = 6 }
\__________/
x¹ + x² = -b/a = -(-5)/1 = 5
x¹ . x² = c/a = 6/1 = 6
__________________
1/( x¹ + x² ) = ⅕
1/( x¹ . x² ) = ⅙
\__________/
x² + ( x¹ + x² )x + ( x¹ . x² ) = 0
x² + ⅕x + ⅙ = 0
30x² + 6x + 5 = 0
Semoga bisa membantu
