The expression ...
... (x+1)/(x²+2x-24)
will have a zero denominator when
... x² +2x -24 = 0
... (x +6)(x -4) = 0 . . . . . factored form
... x = -6, x = 4 . . . . . . . values of x that make the factors zero
The rational expression will be undefined when x = -6 or x = 4.
The answer is inches
Step 1. Subtract length of the door from the width of the door:
Step 2. You want the same space to be on each side of the bar. So, divide the difference from step 1 by 2:
If you use the midpoint formula which is [(X1+X2)/2,(Y1+Y2)/2], you will get your midpoint is [(a+b)/2,(b+c)/2]
