My friend is stuck on a math question. You have to factor two numbers and turn it into 4 numbers (I got stuck cause it made no sense to me). So like, you have to factor a polynomial and make it into 4 numbers into one (no brackets... would it be called a quadromial? I don't think it would be...)
So you have 3x2 - 75
3x2=3 squared
We think it has to do with the greatest common factor (which would be 3).
Any idea? (if you get it and can get an answer, can you show the work?)
I know there isn't much info but that's all I can explain cause it's on a sheet with a pile of other answers and the answers each have a word and when you put it into a spot on the sheet it'll make a (logical) sentence...

You're right, that's not much to go on ☺
But I think you have
3x²-75 which is
3(x²-25) and (x²-25) is the differene of perfect squares so it becomes
3(x+5)(x-5)

Ok, so you have 3x^2 - 75 to factor,... here goes....
1) Factor out a 3.
3 (x^2 - 25)
2) Now you're left with a simple "difference of 2 squares factorization.
3 (x+5)(x-5)
