Answer
$x^3+2x^2-14x+5$
Work Step by Step
$\ \ \ \ \ \ \ \ \ \ \ \ x^2-3x+1$
$\underline{\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x+5}$
$\ \ \ \ \ \ \ \ \ 5x^2-15x+5\longrightarrow$ multiply by 5
$\underline{x^3-3x^2+\ \ \ \ x\ \ \ \ \ \ \ }\longrightarrow$ multiply by x
$x^3+2x^2-14x+5\ \longrightarrow$ combine like terms
