Question

factorize x3+13n2+32n+20​

Answer 1

Answer:

$x^3+13n^2+32n+20\\x^3+n(13n+32)+20$

It cannot be futher factored, but if you're looking for  $x^3+13x^2+32x+20$

It can be factored using the Rational Root Theorem

$\frac{x^3+13x^2+32x+20}{x+1}=x^2+\frac{12x^2+32x+20}{x+1}$

$=x^2+12x+\frac{20x+20}{x+1}$

$=x^2+12x+20$

$=\left(x+1\right)\left(x+2\right)\left(x+10\right)$
