## tiph 3 years ago Part 1: Simplify the complex fractions. (4 points) the quantity x¨Csquared minus x minus 20 over 4 all over the quantity x minus 5 over 10 and the quantity x¨Csquared minus x minus 20 over x minus 5 all over the quantity 4 over 10 Part 2: Are the complex fractions equivalent? Explain why or why not. (4 points)

I get the first part I just don't get if its equivalent or not??

Is what you're trying to say: (C^2-(x-(20/4)))/x - 5/10 ? Could you please write it out in numbers?

Even though there are quadratic formulae there, it's still just dividing fractions. Think of it as: $\frac{ x ^{2}-x-2 }{ 4 } \times \frac{ 10 }{ x-5}$ and $\frac{ 10 }{ x-5 } \times \frac{ x ^{2}-x-2 }{ 4 }$ are they equal to each other :)?

i think are equal but for some reason im just second guessing myself?

6. cathyangs

:) Well, if you're uncertain, you could try solving both sides. I'd advise doing the fraction division using the equations I wrote in LaTeX up there ^. Fyi, I would say they are equal.

ok thanks. I will do that (:

You're welcome! I'm glad I could help.
