The method name reflects the number of parameters:
anObject unaryMessage. "unary message takes no parameters" anObject + anotherObject. "binary message is punctuation, takes one parameter" anObject takes: aParameter and: anotherParameter "keyword message"
A keyword message takes one parameter following each colon-terminated word. In this case, the name of the message is "takes:and:".
For a solver, you'd probably have:
result := theSolver solveQuadraticEquationForA: a andB: b andC: c.
or something like that.
