You need to know how to do math at a decent level to perform in any science or technology job. But I'll be more specific: in chemistry, you explicitly need quadratic equations to solve acid/base equilibrium problems: i.e. the degree to which an acid or base dissociates in water. Even more specifically, you need acid/base equilibrium math to do calculations for buffered solutions: i.e. the amount of a conjugate base needed in combination with its acid to maintain pH in a narrow range, which is extremely important in biological systems. Sure, you say calculators can solve these problems, but you need to understand quadratic equations to set up the problem in the first place.
