Question 625235: I have a few questions.
1. Subtract and express in simplest form ; (1/(x^2-x-6))-(1/(x^2-9))
The answer I got was (5/(x-3)(x+3)(x+2) is that correct?
2. a. Determine the length of AB. A (-8,2) B(5,-8).... my answer was sprt(269)
b. Determine the midpoint of line segmaent AB.... ((-3/2,-3) is what I got
c. Find the equation of a circle whose diameter is line segment AB
(x+3/2)^2+(y+3)^2=67.25 was what I got
d. What is the radius and the center of the circle. radius... 8.20 and center (-3/2,-3)
Are these answers correct.
