factor x23x+4

(x4)(x+1)

i tried that one it doesn't work because that equals x23x4 I need x23x+4

Sorry she made a mistake you need to use the quadratic formula which you can find on youtube.

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^24ac) /2
x=3/2 + 1/2 sqrt (916)
x= 1.5 +i/2 sqrt7
(x1.5+isqrt7/4)(x1.5isqrt7/4)
check that. 
Unless the expression was
x²4x+3
which you can factor.
Check the question.
