Thank you so much, im doing my homework right now and thankfully this is one of the questions. God Bless you.

So everyone is confused is let me clear this up
2x is the cube of 8x because 2•2•2= 8 and 5 is is 125 because 5•5•5= 125 so that’s how you get (2x+5)

You didn't explain anything, in fact I'm even more confused, why is a=2x and b=5?

[ChavoMysterio]

8x^3+125
(2x)^3+(5)^3

A^3+B^3=(A+B)(A^2-AB+B^2)

(2x+5)(4x^2-10x+25)
