Holy Catfish, Miss Olivia!! I don't understand that one either. But then, I don't understand a lot of things.
I don't worry much about it, though. AEN

x^2 - 3x + 7 is positive for all values of x -- therefore there are no real roots and it can't be factored using real coefficients. You can draw a graph in Excel to verify this if you like.
Its minimum point is at x = 3/2
You can use the quadratic formula to find its two roots in the Complex Numbers and factor it into two linear factors with complex coefficients. But I doubt that is required for your problem.

if you only want to know if its factorable the answer is No
{0} but it can be solved by using completing the square method.
3/2^2=9/4
x^2-3x+9/4=-7+9/4
(X-9/4)^2=37/4 square root that and have sq root 37 over 2
