Solution for s=(pi)rs+(pi)r^2 equation:


Simplifying
s = (pi) * rs + (pi) * r2

Multiply ip * rs
s = iprs + (pi) * r2

Multiply ip * r2
s = iprs + ipr2

Solving
s = iprs + ipr2

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-1iprs' to each side of the equation.
-1iprs + s = iprs + -1iprs + ipr2

Combine like terms: iprs + -1iprs = 0
-1iprs + s = 0 + ipr2
-1iprs + s = ipr2

Reorder the terms:
-1iprs + -1ipr2 + s = ipr2 + -1ipr2

Combine like terms: ipr2 + -1ipr2 = 0
-1iprs + -1ipr2 + s = 0
