Question

if alpha and beta are the roots of ax square_bx+c=0(a is not equal to zero) then calculate alpha + beta

Answer 1

answer
alpha + beta = -b/a

Answer 2

Good question


Here is your answer



♣♣♣♣♣ Alpha +Beta = -b / a ♣♣♣♣♣



but now one question comes in your mind why and how

so here is your answer

we call alpha and beta are zeroes of quadratic polynomial

In this we have ax^2 +bx +c = 0

Then ingoring cofficient see the degree of polynomial
2 , 1 , constant

so when we have alpha +beta &&& alpha × beta we verified our zeroes obtained from any quadratic equation
