    x = 2, 1

    Step-by-step explanation:

    so first we want to factor, this one is a simple one to factor since it doesn't have a number other than 1 in the first term

    what multiplies to 2 and adds to - 3

    -2 and - 1

    so we set out our binomials as

    (x - 2) (x - 1)

    then we set each of these to zero (of course it's easier just to swith the signs, but it doesn't work the same if there is a number other the one in front of the x ... EX: (2x-2) (3x + 4))

    x - 2 = 0

    +2 + 2

    x = 2

    and

    x - 1 = 0

    +1 + 1

    x = 1

    so the solution, or the zeroes are x = 2, 1
