This might seem like a very silly question, but oh well: what is the significance of the number b in x2 + bx?
x^2 + bx , that is
It just means you multiply x times b
So, if you knew that b was, say, 12, then you would have:
x^2 + 12 × x
if the equation is x^2 + bx = 0, then b is the negative location of the second root (the first being 0). In other words, -b is a root of the equation.
"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."
The larger b is, then the parabola is bent more upward as you go right?
Just a guess.
If b is negative then the parabola is bent more downward as you go right?

You're thinking of when it is something like bx².
When it is x² + bx, the graph shifts more to the left as b increases and more downward as |b| increases.
Why did the vector cross the road?
It wanted to be normal.
