If ` x + 1/x = a, x^(2)+1/x^(3) = b," then "x^(3) + 1/x^(2)` is-

(b) If (x^(2)+1)/(x)=3(1)/(3) and x>1 ; find x^(3)-(1)/(x^(3))

If x_(1),x_(2),x_(3) are the roots of x^(3)+ax^(2)+b=0, the value of x_(2)x_(3),x_(1)x_(3),x_(1),x_(2)]|

int(x+1)/(x^(1//2)) dx= a) -x^(3//2)+x^(1//2)+c b) x^(1//2 c) 2/3x^(3//2)+2x^(1//2)+c d) x^(3//2)+x^(1//2)+c

If (1 -2x)/(3 + 2x - x^(2)) = (A)/(3 -x ) + (B)/(x + 1) ,then the value of A + B is
