Description

• 

The IsQuadraticFormula command returns true when the input expr matches the quadratic formula.

• 

The quadratic formula can be written in many subtly different ways, including use of &+- as opposed to ±, and use of different variable names.  This command helps to identify input steps that match a declared unevaluated quadratic formula with symbols for a, b, and c.  

• 

This command is used by Grading:-SolveFeedback to identify a step in a solution input that matches the quadratic formula.
