Answer:

a²/4 + 1/a² =5

Step-by-step explanation:

a²/4 + 1/a² = ?

Given,

7 a/2 + 14 = 7/a

Divide the equation by 7 we get

a/2 + 2 = 1/a

a/2 - 1/a = - 2

squaring both side and apply (a-b)² identity.

(²a/2 - 1/a) = (- 2)²

a²/4 + 1/a² - 2 * a/2 * 1/a = 4

a²/4 + 1/a² = 4 + 1 = 5

Hence, a²/4 + 1/a² =5
