(2)/(3)x^2-(17)/(3)x-28

3x-(5x^(2))/(2)+(9x^(3))/(3)-(17x^(4))/(4)+....+(-1)^(n-1)((2^(n)+1))/(2)x^(n)+...=

If a,b are roots of 3x^(2)-4x-2=0, then value of 3a^(2)+7b-(2)/(b) is equal to (a) (16)/(3) (b) (34)/(3)(c)(17)/(5)(d)(28)/(5)

If sqrt(3)sin pi x+cos pi x=x^(2)-(2)/(3)x+(19)/(9) then x os equal to

(x^(4)+24x^(2)+28)/((x^(2)+1)^(3))=

Prove that (cos(9x)-cos(5x))/(sin(17x)-sin(3x))=-(sin(2x))/(cos(10x))

Solve the equation (x^(2)-3x)^(2)+3x^(2)-9x-28=0 for real roots.
