Let `f(x)=ax^2 + bx+c` whose roots are `alpha` and `beta` ,` a ne 0` and `triangle=b^2-4ac`. If `alpha + beta , alpha^2 + beta^2 ` and `alpha^3 + beta^3` are in GP then :

Let f(x) = ax^(2) + bx + c, a != 0 and Delta = b^(2) - 4ac . If alpha + beta, alpha^(2) + beta^(2) and alpha^(3) + beta^(3) are in GP, then

Let f(x) = ax^(2) + bx + c, a != 0 and Delta = b^(2) - 4ac . If alpha + beta, alpha^(2) + beta^(2) and alpha^(3) + beta^(3) are in GP, then
