factor x2-3x+4

• elementary functions -

(x-4)(x+1)

• elementary functions -

i tried that one it doesn't work because that equals x2-3x-4 I need x2-3x+4

• elementary functions -

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

• elementary functions -

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

• elementary functions -

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.
