Hello, I just need a short explanation on these problems I've had a little trouble solving.
"Solve"
*2y/y+2= y/y+3-3/(y+2)(y+3)
"Factor Completely"
*25c^2-10cd+d^2
"Word problem:"
Part of a 50ml bottle of a 40% acid solution is used for a project. The bottle is then refilled with a 10% acid solution. Once it has been refilled it is then a 25% acid solution. How much of the original solution was used in the project.
Thank you, I have my own answers for the first two I'm just not completely sure.
