Question 62247
1-49/x^2
________
7/x+1 
--------------
[1-(49/x^2)]/[7/(x+1)]
Simplify the numerator:
[(x^2)-49)/x^2]/[7/(x+1)]
Invert the denominator and multiply:
[(x^2)-49)/x^2]*[(x+1)/7]
There are no common factors you can cancel.
So, multiply the numerators and the denominators as is:
[(x^2-49)(x+1)]/7x^2]
