hello i was asked to solve the real value of x for which
i got and but the answer in the book is can some one please show me how this answer is arrived at..
So first you need to solve for all the zero points of the numerator and denominator
They are and
This divides the number line into three disjoint parts i.e
Now just check test points in each regions
So if we check we get
So the first set is not a solution. Now just check the other two and you will find that the middle one is the only one that checks.
