25x4 + 13x - 13x - 64

25x4 + 40x - 40x - 64

(5x2 + 8) (5x2 - 8)

Step-by-step explanation:

firstly, subtract 4-64 from 25x4-64 gives us 25x-60

1. 13x-13x = 0 so they cancel out. so it is left with: 25x4-64 = 25x-60

2. same thing. 40x-40x = 0 and 4-64 is = - 60 left with: 25x-60

3. you add 2+8 and 2-8 which will be: (5x+10) (5x-6)

-then you multiply 5x*5x, then again multiply 10*-6

and it gives you 25x-60
