Hi, just starting chapter review of Algebra 1. The first question is:
Show that the following simplifies to a constant when x =/= 1/2:
x - 1 3 - 7x
------- + -------
2x - 1 1 - 2x
I have no idea how to tackle this. I can see that if x = 1/2, you're going to be dividing by zero on both sides, which will give non-real numbers (imaginary?) because anything divided by zero is like, infinity.
BUT how do you show it simplifies to a constant? Do I just find a common denominator, add and simplify? Is that it?
Thanks in advance to anyone who can answer this for me!
