Question

(2a+1/2a)²+(2a-1/2a)²​

Answer 1

Step-by-step explanation:

= (2a+1/2a)²+(2a-1/2a)²

= 4a² + a² + 1/4 a² + 4a² - a² + 1/4 a²

= 8a² + 1/2a²

= 17/2a²

Answer 2

Answer:

$4a ^{2} + \frac{1}{4a {}^{2} } + 2 + 4a^{2} + \frac{1}{4a^{2} } - 2 \\ 8a^{2} + \frac{2}{4a^{2} } \\ 2(4a^{2} + \frac{1}{4 {a}^{2} } )$
