Question

write the formula of alpha beta ??​

Answer 1

Answer:

As discussed in the Linear Quadratic Equation topic, the alpha/beta values describe the curvature of a cell survival curve. The alpha/beta ratio is the dose where cell killing due to the linear and quadratic components are equal. ... The higher the alpha/beta ratio, the more linear the cell survival curve will be.

Step-by-step explanation:

There are three roots of a cubic equation given by α (Alpha), β (Beta) and γ (Gamma). α + β + γ = -b/a i.e sum of roots = -b/a. α β + β γ + αγ = c/a i.e products of roots taken 2 at a time = c/a. αβγ = -d/a i.e. Product of roots = -d/a.

Answer 2

Answer:

Find the quadratic equation with roots α and β given α − β = 2 and α2 − β2 = 3. We'll set up a system of two equations in two unknowns to find `alpha` and `beta`. Since `(alpha + beta) = 3/2` then `beta = 3/2 - alpha`, giving us `beta = -1/4`.
