Bantuin dong pleasee

Answer 1

  2            1
-------  +  ---------  = 2
x - 2        x + 3

samakan penyebutnya:

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

     2x + 6 + x - 2
⇔ --------------------- = 2
   x² + 3x - 2x - 6

⇔ 3x + 4 = 2 ( x² + x - 6 )
⇔ 3x + 4 = 2x² + 2x - 12
         0 = 2x² + 2x - 3x - 12 - 4
         0 = 2x² - x - 16
jadi, a= 2, b= -1, c = -16
