Respuesta :
Factoring out (x-3), we get (7x^2+5) (x-3). That is your answer, I hope this helps :).
The given polynomial is :
[tex]7 x^3-21 x^2+ 5 x - 15[/tex]
Factorizing it by taking common factor among two terms
→7 x²(x-3) + 5 (x-3)
Taking (x-3) , common between two terms of the above expression, then the given expression is reduced in the form of,
→(x-3)(7 x² +5)→→Completely factored form of polynomial [tex]7 x^3-21 x^2+ 5 x - 15[/tex]
