Factorize x3+13n2+32n+20​

Answer»

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)
