Question

i want all the important formulaes for the chapter polynomials . ( alpha , beta )

Answer 1

If \alpha & \beta are the zeroes of polynomial ax^2 + bx + c, then
 $\alpha + \beta = - b divided by a$
 $\alpha \beta = c divided by a$
If [tex] \alpha , \beta and gama are the zeroes of polynomial a x^3 +b x^{2} + cx + d = 0, then [/tex]
alpha + beta + gama = -b/a
alphabeta + betagama + gamaalpah = c/a
alphabetagama= -d/a
