but were it is i can't find.u send me the attached file
given - alpha + beta + gama = 1
alphabeta + betagama + alphagama = 3
alphabetagama = 6
fomula - x3 - (alpha + beta + gama) x2 + (alphabeta + beta gama + alpha gama)x -alpha
alpha beta gama
= x3 - x2 + 3x -6
alphabeta + betagama + alphagama = 3
alphabetagama = 6
fomula - x3 - (alpha + beta + gama) x2 + (alphabeta + beta gama + alpha gama)x -alpha
alpha beta gama
= x3 - x2 + 3x -6
