If 3x - (1)/(3x ) =5 , find : (i) 9x^(2) + (1)/( 9x^2)

The locus of the point which divides the double ordinates of the ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1 in the ratio 1:2 internally is (x^(2))/(q^(2))+(9y^(2))/(b^(2))=1 (b) (x^(2))/(a^(2))+(9y^(2))/(b^(2))=(1)/(9)(9x^(2))/(a^(2))+(9y^(2))/(b^(2))=1( d) none of these

If 3x + (1)/(3x) = 3 , find : (i) 9x^(2) + (1)/(9x^2)

(a) Factorise : 9x^(2) - 24 xy + 16y^(2) (b) Factorise : 25x^(2) + (1)/(25x^(2)) + 2

If int(sqrt(1-x^(2)))/(x^(4))dx=A(x)*(sqrt(1-x^(2)))^(m) where A(x) is a function of x then (A(x))^(m)= (A) -(1)/(27x^(9))(B)(1)/((27x)^(9))(C)(1)/(3x^(9))(D)-(1)/(3x^(9))
