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.

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?

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.

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

Hey guys.

This might seem like a very silly question, but oh well: what is the significance of the number b in x2 + bx?

thank yooo
