The other factors of the polynomial are (x-7) and (x - 3)
What is a polynomial?
A polynomial is an algebraic expression with at least the power index of its variable 2.
Analysis:
[tex]x^{3}[/tex] -15[tex]x^{2}[/tex]+71x-105/x-5 Reduces to [tex]x^{2}[/tex] -10x + 21
solving further,
[tex]x^{2}[/tex] -7x -3x + 21
x(x-7) -3(x-7)
(x-3)(x-7)
The two other factors of the polynomial are (x-7) and (x-3)
