Question

X Plus One by X equal to a and X square + 1 by excuse equal to b then x cube + 1 by x squared equal to

Answer 1

x+1/x=a
x²+1/x³=b
x³+1/x²=?------1
(x²+1)/x=a
x²+1=ax
x²=ax-1-------eqn2
x²+1/x³=b
(x^5+1)/x³=b
x^5+1=bx³
x³=(x^5+1)/b-------eqn3
putting value of x³and x² from eqn2$3in eqn 1
x³+1/x²=
(x^5+1)/b+1/ax-1
