  • 1) (a + 4)(a + 4)
    = a² + 8a + 16

    2) (x - 6)(x - 4)
    = x² - 10x + 24

    3) (a - 3)(x - 4)
    = ax - 3x - 4a + 12

    4) (2x - 2)(x + 5)
    = 2x² + 8x - 10

    5) (-3a + 6)(2a - 3)
    = - 6a² + 12a + 9a - 18
    = - 6a² + 21a - 18

    6) (-2a - 4)(-3a + 1)
    = 6a² + 12a - 2a - 4
    = 6a² + 10a - 4

    7) (-3x - 2)(-4x + 5)
    = 12x² + 8x - 15x - 10
    = 12x² - 7x - 10
