Answer 1

Eric, recheck it.

\((a+b)^2= a^2 + b^2 +2ab\)

here, you have a = x^2 and b = 5^2

Answer 2

wait u know the rule , just set up it correctly :D

Answer 3

in the first and second terms, x and 5 are raised to the fourth power not the second. and in the last term five should be squared.
so you will end up with x^4+5^4+2(x^2)(5^2)

Answer 4

Understood
