What is Veda's law?

What is Veda's law?

In the univariate quadratic equation AX ^ 2 + BX + C = 0 (a ≠ 0 and △ = B ^ 2-4ac ≥ 0)
Let two roots be X1 and x2
Then X1 + x2 = - B / A
X1*X2=c/a
The generalization of Weida's theorem
Generally, for an equation of degree n with one variable ∑ AIX ^ i = 0
Its roots are recorded as x1, X2 ,Xn
We have
∑Xi=(-1)^1*A(n-1)/A(n)
∑XiXj=(-1)^2*A(n-2)/A(n)
…
∏Xi=(-1)^n*A(0)/A(n)
Where ∑ is the sum and Π is the product
