A polynomial is one possible answer.
It means "a Mathematical Expression".
"An expression of three terms" means that the expression has three parts, combined by plus or minus signs. Within each of these parts (terms), there can be a single number or variable, or a product or division involving several other pieces.
It's a risk.
