So, I got a few problems in my work like this:
v^2-16 , V^2-9v+20
the directions say "Find equivalent expressions that have the least common denominator"
The example when solved, looks like this:
then it has me do the same with the second problem, which ends up looking like this:
I want to figure out how to calculate these kinds of problems in Wolfram|Alpha, I've tried just about everything. I can't even search the internet for how to solve these, as I don't even know what kind of problems these are classified as.
