Answer:
A = ![\frac{b}{f^2+2H}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7Bf%5E2%2B2H%7D)
Step-by-step explanation:
Given equation is,
b = f²A + 2HA
To solve this equation for the value of A we will isolate A in one side of the equation.
b = A(f² + 2H)
By dividing the equation by (f² + 2H) on both the sides of the equation.
![\frac{b}{f^2+2H}=\frac{A(f^2+2H}{(f^2+2H)}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7Bf%5E2%2B2H%7D%3D%5Cfrac%7BA%28f%5E2%2B2H%7D%7B%28f%5E2%2B2H%29%7D)
A = ![\frac{b}{f^2+2H}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7Bf%5E2%2B2H%7D)
Therefore, answer will be A = ![\frac{b}{f^2+2H}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7Bf%5E2%2B2H%7D)
