105y2z
The LCM is 245z7
25y2 - 49w2 = (5y)2 - (7w)2 = (5y - 7w)(5y + 7w)
the sum of 35 and z 35z
3/35z
200xy2
6xy over 105xyz = 2/35z
The one which says: y2 = 4 - 4/25 x2

I think that wants to be 16x2 - 40xy + 25y2 That factors to (4x - 5y)(4x - 5y) or (4x - 5y)2
Eh-36-35Z is just regular EH-36 plate that has been Impact tested in the "Z" direction at typically -40 F.
The LCM is: 210
