Ok I have to identify the extram i.e.the maximum and minimum points of this function and...i'm kinda confused
Thats what i got for my derivative so i just factor out numerator and denominator right?
as my zeroes
Remember! Division by zero is not defined.
skeeter got the roots excluding and by separating the contents using the formula for the difference of two squares,
that is , just as he had written, because .
Now, considering that division by zero isn't defined, what has to be zero for the fraction to equal zero?
