Answer:

$-32x^5-400x^4-2000x^3-5000x^2-6250x-3124$

Step-by-step explanation:

So what we should do is first expand. What I did was I did it one step at a time, starting with (2x+5)(2x+5). This gave me $4x^2+20x+25$ . I then continued to do this, until I got $32x^5+400x^4+2000x^3+5000x^2+6250x+3125$ . Then you asked me what this would be subtracted from 1. So, what I did was set it so that it would follow this rule, making it $1-(32x^5+400x^4+2000x^3+5000x^2+6250x+3125)$ .

After this, I just simplified.
