If $a = 0$ , then the equation is linear, not quadratic. The numbers $a$ , $b$ , and $c$ are the coefficients of the equation, and may be distinguished by calling them, respectively, the quadratic coefficient, the linear coefficient and the constant or free term. 近义、反义、联想词近义词 n. equation 英英词典 quadratic equation n. an equation in which the highest power of an unknown quantity is a square synonymous： quadratic
