Also know, what is Alpha Beta in quadratic equation?
alpha , beta be the roots of the quadratic equation (Since only 2 roots can exist for a quadratic equation) We know that, sum of roots=alpha + beta = -b/a=> eqn (1) product of roots=alpha*beta=c/a=>eqn (2) (a+b)^2=a^2+b^2+2*a*b.
Similarly, what is alpha plus beta? If it is a quadratic equation then it's zeroes are alpha and beta. Sum of zeroes is -b/a. So alpha plus beta is -b divided by a.
Also know, what is the sum of alpha and beta?
Thus, if a quadratic has two real roots α,β, then the x-coordinate of the vertex is 12(α+β). Now we also know that this quantity is equal to −b2a. Thus we can express the sum of the roots in terms of the coefficients a,b,c of the quadratic as α+β=−ba.
What is alpha and beta?
Alpha is the excess return on an investment relative to the return on a benchmark index. Beta is the measure of relative volatility. Alpha and beta are both risk ratios that calculate, compare, and predict returns.
