-2x(3x+4) =-7+3x pakai cara yg jelas yaa bsok dkmpl nih ——– 5

– 2x(3x + 4) = – 7 + 3x
– 6x² – 8x = – 7 + 3x
– 6x² – 8x – 3x + 7 = 0
– 6x² – 11 x + 7 = 0    …kalikan dengan – 1
  6x² + 11x – 7 = 0
 (3x + 7)(2x – 1) = 0
 3x + 7 = 0  atau   2x – 1 = 0
      3x  = – 7  atau  2x = 1
        x = -     atau  x =
