Rearrange formulas to isolate a chosen quantity, including formulas with quadratic terms.
State restrictions when rearranging a formula
Problem
What restrictions are needed when solving \(r=d/t\) for \(t\)?
Big Picture
What this problem is really about
Restrictions come from both the original formula and the operations used while rearranging it. We’ll protect the original denominator, inspect the new denominator created when isolating t, and require the resulting quotient to remain nonzero so it still belongs to the original domain.
