If `alpha_1, ,alpha_2, ,alpha_n` are the roots of equation `x^n+n a x-b=0,` show that `(alpha_1-alpha_2)(alpha_1-alpha_2)(alpha_1-alpha_n)=n(alpha1n-1+a)`

If 1,alpha_1, alpha_2, …alpha_(n-1) be n, nth roots of unity show that (1-alpha_1)(1-alpha_2).(1-alpha(n-1)=m

If the roots of equation x^3+a x^2+b=0a r ealpha_1,alpha_2 and alpha_3(a ,b!=0) , then find the equation whose roots are (alpha_1alpha_2+alpha_2alpha_3)/(alpha_1alpha_2alpha_3),(alpha_2alpha_3+alpha_3alpha_1)/(alpha_1alpha_2alpha_3),(alpha_1alpha_3+alpha_1alpha_2)/(alpha_1alpha_2alpha_3)

If the roots of equation x^(3) + ax^(2) + b = 0 are alpha _(1), alpha_(2), and alpha_(3) (a , b ne 0) . Then find the equation whose roots are (alpha_(1)alpha_(2)+alpha_(2)alpha_(3))/(alpha_(1)alpha_(2)alpha_(3)), (alpha_(2)alpha_(3)+alpha_(3)alpha_(1))/(alpha_(1)alpha_(2)alpha_(3)), (alpha_(1)alpha_(3)+alpha_(1)alpha_(2))/(alpha_(1)alpha_(2)alpha_(3)) .

If 1,alpha_(1),alpha_(2),………..,alpha_(n-1) are nk^(th) roots of unity, then the value of (1-alpha_(1))(1-alpha_(2))(1-alpha_(3))……(1-alpha_(n-1)) is equal to

If 1,alpha_(1),alpha_(2),alpha_(3),...,alpha_(n-1) are n, nth roots of unity, then (1-alpha_(1))(1-alpha_(2))(1-alpha_(3))...(1-alpha_(n-1)) equals to

If alpha_(1),alpha_(2),alpha_(3)......alpha_(n) are roots of the equation f(x)=0 then (-alpha_(1),-alpha_(2),-alpha_(3),......alpha_(n)) are the roots of

If 1,alpha_(1),alpha_(2),...,alpha_(n-1) are the nth roots of unity,prove that (1-alpha_(1))(1-alpha_(2))...(1-alpha_(n-1))=n. Deduce that sin(pi)/(n)sin(2 pi)/(n)...sin((n-1)pi)/(n)=sin(n)/(2^(n-1))

If 1,alpha_(1),alpha_(2),…………….,alpha_(n-1) are n^(th) roots of unity and n is an even natural number, then (1+alpha_(1))(1+alpha_(2))(1+alpha_(3))……(1+alpha_(n-1)) equals
