Best ResponseYou've already chosen the best response.0alpha and beta are like variables. So they are two unknown values. (just like x, y, z, a, etc.)

Best ResponseYou've already chosen the best response.0It means that the graph of the equation, y = a*x^2 + b*x + c, crosses the xaxis (xintercept) at x = alpha and x = beta. Sometimes these are called your "roots of y" or "zeros of y."
