UPDATE:
My Math Teacher just said it was a typo, where he forgot to add a negative two, so that the piecewise function would be:
f(x):
Ax^2 - Bx - 2, X ≤ 1
Alnx + B, X > 1
Now solving it, I got A = -2 and B = -2.
Probably should have put this in earlier as proof of the existence of the problem.
Hopefully links are fine. Sorry if it isn't allowed.

Homework Statement
Find the values of a and b that make f a differentiable function.
Note: F(x) is a piecewise function
f(x):
Ax^2 - Bx, X ≤ 1
Alnx + B, X > 1
Homework EquationsThe Attempt at a Solution
Made the two equations equal each other.
Ax^2 - Bx = Alnx + B
Inserting x=1 gives,
A - B =...
