    will that help me to factor the equation because I did it and I got 3+ or - 5i all over 2 and that's not going to help me factor the equation

    Well, it does.

    x= -b+-sqrt(b^2-4ac) /2

    x=3/2 +- 1/2 sqrt (9-16)

    x= 1.5 +-i/2 sqrt7

    (x-1.5+isqrt7/4)(x-1.5-isqrt7/4)

    check that.

    Unless the expression was
    x²-4x+3
    which you can factor.
    Check the question.
