    Step-by-step explanation:

    (1) x²-3x

    = x(x-3)

    (2) 12a²b-6ab²

    = 6ab(2a-b)

    (3) 20x²-9x+1

    = 20x²-5x-4x+1

    = 5x(4x-1)-1(4x-1)

    = (4x-1) (5x-1)

    (4) -6-x+x². ( correction applied. +6 => -6)

    = x²-x-6

    = x²-3x+2x-6

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

    = (x-3)(x+2)

    Hope this helps you
