  • 1. ( 2x - 3 ) ( 3x - 4 )
    = 6x^2 - 8x - 9x + 12
    = 6 x^2 - 17x + 12

    2. ( 2x + 3 ) ( x + 4 )
    = 2x^2 + 8x + 3x + 12
    = 2x^2 + 11x + 12

    3. ( 3x + 1 ) ( 2x + 2 )
    = 6x^2 + 6x + 2x + 2
    = 6x^2 + 8x + 2
  • Materi Aljabar

    1. (2x-3)(3x-4) = 2x(3x-4)-3(3x-4) = 6x^2-8x-9x+12 = 6x^2-17x+12
    2. (2x+3)(x+4) = 2x(x+4)+3(x+4) = 2x^2 + 8x + 3x + 12 = 2x^2 + 11x + 12
    3. (3x+1)(2x+2) = 3x(2x+2)+1(2x+2) = 6x^2 + 6x + 2x + 2 = 6x^2 + 8x + 2
