Question

if alpha and beta are the zeroes of a polynomial x^2-4√ 3x +3 , then find the value of alpha +beta -alpha beta

Answer 1

sum of the roots is -b/a and product of the roots is c/a

Answer 2

alpha + beta = sum of the roots =-b/a
alpha+beta= -(-4root3)/1= 4root3
alphabeta= product of the roots= c/a
alphabeta= 3/1=3
alpha +beta - alphabeta
4root3-3 is the obtained answer
