[tex] \frac{1}{x1 \: } + \: \frac{1}{x2} [/tex]
​

Answer 1

Persamaan Kuadrat

..

Penyelesaian Soal

2x² + 5x - 3 = 0

2x² + 6x - 5x - 3 = 0

2x(x + 3) - (x + 3) = 0

(x + 3)(2x - 1) = 0

..

x1 = - 3

x2 = 0,5

..

1/x1 + 1/x2

= - 1/3 + 1/0,5

= - 1/3 + 2

= - 1/3 + 6/3

= 5/3

= [tex]1 \frac{2}{3}[/tex]
