Flowchart showing the three brackets (x+3), (x+4), and (x+2) becoming a quadratic and then a cubic during expansion

A triple bracket such as (x+2)(x+5)(x−1)(x+2)(x+5)(x-1)(x+2)(x+5)(x−1) means three linear factors are being multiplied together. The safest method is to expand any two brackets first, simplify to a quadratic, then multiply by the remaining bracket.
