Answer 1

Answer:

4^2−4+20+^2−10+25^2

Step-by-step explanation:

(2−+5)^2

(2−+5)(2−+5)

2(2−+5)+(2−+5)(−)+5(2−+5)

4^2−2+10+(2−+5)(−)+5(2−+5)

4^2−2+10−(2−+5)⋅+5(2−+5)

4^2−2+10−(2−+5)+5(2−+5)

4^2−2+10−(2−^2+5)+5(2−+5)

4^2−2+10−2+^2−5+5(2−+5)

4^2−2+10−2+^2−5+10−5+25^2

4^2−4+10+^2−5+10−5+25^2

4^2−4+20+^2−5−5+25^2

4^2−4+20+^2−10+25^2
