I think you got your answer.
Its 25* 9xsquared.
All you have to do is FOIL it.
Multiply the first two numbers together which would be 5 and 5.
The outer numbers which would be 5 and 3x.
Etc...

u distribute it out - FOIL
25 + 15x - 15x - 9x^2
the combine like terms - the middle terms cancel out so you have this left (sorry i have a laptop so cant use the alt codes)
-9x^2 + 25
