IF alpha , beta are the roots of x^2 - ax +b=0 , then the whose roots are (alpha + beta ) /( alpha ) , (alpha + beta)/( beta) is

If alpha and beta are the zeros of the quadratic polynomial f(x)=a x^2+b x+c , then evaluate: (i) beta/(aalpha+b)+alpha/(abeta+b) (ii) a((alpha^2)/beta+(beta^2)/alpha)+b(alpha/beta+beta/alpha)

a((alpha^(2))/(beta)+(beta^(2))/(alpha))+b((alpha)/(beta)+(beta)/(alpha))

If alpha,beta are non-real roots of ax^(2)+bx+c=0,(a,b,c in R), then (A)alpha beta=1(B)alpha=beta(C)(a beta)/(alpha beta)=1(D)alpha=bar(beta)

If alpha, beta are the roots of the quadratic equation x^2 + bx - c = 0 , the equation whose roots are b and c , is a. x^(2)+alpha x- beta=0 b. x^(2)-[(alpha +beta)+alpha beta]x-alpha beta( alpha+beta)=0 c. x^(2)+[(alpha + beta)+alpha beta]x+alpha beta(alpha + beta)=0 d. x^(2)+[(alpha +beta)+alpha beta)]x -alpha beta(alpha +beta)=0

If alpha, beta are the roots of the quadratic equation x^2 + bx - c = 0 , the equation whose roots are b and c , is a. x^(2)+alpha x- beta=0 b. x^(2)-[(alpha +beta)+alpha beta]x-alpha beta( alpha+beta)=0 c. x^(2)+[(alpha + beta)+alpha beta]x+alpha beta(alpha + beta)=0 d. x^(2)+[(alpha +beta)+alpha beta)]x -alpha beta(alpha +beta)=0

(sin(alpha+beta))/(sin(alpha-beta))=(a+b)/(a-b) then (tan alpha)/(tan beta)=

Write the formula: alpha^3+beta^3 =…………….a) (alpha+beta)^3-3alphabeta(alpha+beta) b) (alpha-beta)^3+3alphabeta(alpha-beta) c) (alpha+beta)^3-3alphabeta(alpha-beta) d) (alpha-beta)^3-3alphabeta(alpha-beta)
