Question

alpha beta all formulas​

Answer 1

Formula of α and β :-

αβ = c/a

α+β = -b/a

for example :-

2x²-4x +9 is a polynomial..

then,

here,

a = 2 , b = -4 , c = 9

so,

αβ = 9/2

α+β = -4/2

here is your answer .....

Answer 2

alpha + beta = -b / a

alpha x beta = c/a

X^2 - (alpha + beta)X + alpha x beta

(quadratic polynomial)

alpha + beta + gamma = - b/a

alphabeta + beta gamma + gamma alpha = c/a

alpha beta gamma = - d/a

X^3 -( alpha + beta + gamma) X^2 - (alphabeta + beta gamma + gamma alpha )X + alpha beta gamma....

( cubic polynomial)

hope it help you....
