If roots of equation 8x^(3)-14x^(2)+7x-1=0 are in geometric progression,then toots are

Prove that sinfrac {pi}{14} is a root of the equation 8x^(3) -4x^(2) - 4x +1 = 0 .

Factorize following expressions (i) x^(2)+3x-40" (ii)"x^(2)+5x-14 (iii) x^2-3x-4" (iv)"3x^2-10x+8

The expression ((x^(3) -1)(x^(2) -9x + 14))/((x^(2) + x +1)(x^(2) - 8x + 7)) simplifies to:

If f(x) = ""^(40)C_(1).x(1-x)^(39) + 2.""^(40)C_(2).x^(2)(1-x)^(38)+3.""^(40)C_(3).x^(3)(1-x)^(37)+ "….."+40.""^(40)C_(40).x^(40) , then the value of f(3) is
