Create and solve one-variable equations and inequalities from contexts using all studied expression types, including simple root functions.
Write and solve a polynomial equation from a context
Problem
Write \(x(x~+~2)(x~+~3)~=~60\) in zero form and find its positive solution to the nearest thousandth.
Big Picture
What this problem is really about
Treat the three related dimensions as factors in one product before doing any algebra. Zero form then turns the context into a polynomial root problem, but the roots are only candidates until the positive-dimension condition is applied. Keep extra digits during the numerical solve so the final rounding does not shift the result.
