Annual percentage yield (APY)
The rate that would give the same return if interest were computed just once a year

Binomial
A polynomial with exactly two terms

Discriminant
For the equation ax 2 + bx + c, the expression b2  4ac; for the equation Ax2 + Bxy + Cy2 + Dx + Ey + F = 0, the expression B2  4AC
