2(x+2y-xy)+5(2x-3y+5xy)

2 Jawaban

  • 2(x+2y-xy)+5(2x-3y+5xy)  = 2x + 4y - 2xy + 10x - 15y + 25xy
                                              = 2x + 10x - 2xy + 25xy + 4y - 15y
                                              = 12x + 23xy - 11y
  • => 2(x + 2y - xy) + 5(2x - 3y + 5xy)
    => 2x + 4y - 2xy + 10x - 15y + 25xy
    => 12x - 11y + 23xy
