Quadratics crossword puzzle

The number D = b2 – 4ac determined from the coefficients of the equation ax2 + bx + c = 0.
a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4.
also sometimes called a root, of a real-, complex- or generally vector-valued function f is a member x of the domain of f such that f(x) vanishes at x; that is, x is a solution of the equation f(x) = 0.
