\[\huge~\rm~3x=2x^2+4\]
We need to get this equation in:
\[\huge~\rm~\bf~ax^2+bx+c\]
form.
Any ideas on how we can do that?
OpenStudy (anguyennn):
would it be 2x^2-3x+4
pooja195 (pooja195):
Correct :-)
\[\huge~\rm~2x^2-3x+4 \]

thats why I am stuck
pooja195 (pooja195):
Exactly that means that the equation cannot be factored
pooja195 (pooja195):
You would need to solve using the quadratic formula but your problem asks to factor it and the equation cannot be factored
OpenStudy (anguyennn):
so how would I do that please and thank you
pooja195 (pooja195):
You can't...your answer would need to be cannot be factored
