Question 1024751
Make A the subject of the formula
Assume the equation is:
{{{P=(n^2+a)/(n+a)}}}
:
multiply both sides by (n+a)
P(n + a) = n^2 + a
;
Distribute the P
Pn + Pa = n^2 + a
:
Subtract Pn from both sides, subtract a from both sides
Pa - a = n^2 - Pn
:
Factor out a
a(P - 1) = n^2 - Pn
:
Divide both sides by (P-1)
a = {{{(n^2 - Pn)/(P - 1)}}}
