How do you solve #6/(x-1) = 9/(x+1)#?
1 Answer
Explanation:
This is a rational equation therefore we have to lead it in a canonical form like:
In order to do this we have to move all the terms on LHS:
Now we could find LCD (less common denominator) that is:
Since a denominator cannot never be zero we have to find the
This is a product, then it's zero when the factors are zero.
Now we can simplyfy the fractions:
and we can simplify the LCD
Move all the
graph{6/(x-1)-9/(x+1) [4.438, 6.335, -0.688, 0.26]}
