Answer 1

Answer:

mark me brainliest

Answer 2

Step-by-step explanation:

by using the identity (a+b)^2=a^2+2ab+b^2

(2x+5)^2 = (2x)^2+2×2x×5+5^2

= 4x^2+20x+25

now, by using identity (a-b)^2=a^2-2ab+b^2

(2x-5)^2 = (2x)^2-2×2x×5+5^2

= 4x^2-20x+25

on solving further,

4x^2+20x+25+4x^2-20x+25

2(4x^2+25)
