Answer:
Length of AB is 12
Step-by-step explanation:
Here, we are concerned with finding the full length of line AB, given the distance between the midpoint of the line AB and the point B itself
What this means is that, the distance of the halfway of the full length is 6
So the total distance would be twice the halfway distance
So if the halfway distance is 6, then the full distance would be 6 * 2 = 12
So the length of AB = 12

4 / x + 4 / [( x - 3) ( x + 3 )] = 3 / ( x - 3 ) / * x ( x - 3 ) ( x + 3 )
Restrictions : x ≠ 0, x ≠ - 3 , x ≠ 3;
4 ( x + 3 ) ( x - 3 ) + 4 x = 3 x ( x + 3 )
4 ( x² - 9 ) + 4 x = 3 x² + 9 x
4 x² - 36 + 4 x - 3 x² - 9 x = 0
x² - 5 x - 36 = 0
x² - 9 x + 4 x - 36 = 0
x ( x - 9 ) + 4 ( x - 9 ) = 0
( x - 9 ) ( x + 4 ) = 0
x - 9 = 0, or : x + 4 = 0
Answer:
x = 9, x = - 4
