b=y-intercept form which is -1 because that is where the line meets the y axis
A binomial squared is written like

So, we have 
So, we want to complete the square 
We can add and subtract 9 to write

P,Q,R can't be 0, because their product is nonzero. Either of S and T could be 0, but the third one only works if S is 0.
