Hi guys so here's a problem that I have stumbled upon while I'm answering a worksheet I've found in the internet. I'm really not sure on how to approach this as I keep on ending up with polynomials that I don't know what to do. I tried to first factor the (b - c)^2, and multiply (b - a)/(a - c) by its conjugate to somehow find something out but I still couldn't see any connections and a next step to do

Tl;dr I'm stuck haha

maybe you can try doing some substitution and use the quadratic formula to find the answer

#

where c is equal to 0

and you'll see the ans

Wait are you using this formula for the 3rd and 4th lines?

#

Yes

#

Where a here, is 2a.

#

by the way do you have any worksheets or any references on algebraic expressions similar to this that I could practice on?

#

I'm weak when it comes to this kind of problems so yeah

factorization worksheets features nine types of algebraic identities and with two levels of difficulty

#

i just googled them, idk if they're gonna help or no... they looked fine
