Answer
$44$.
Work Step by Step
The given expression is
$=4x^3+3x^2-x+2$
Substitute $x=1$.
$=4(1)^3+3(1)^2-(1)+2$
Use $1^3=1$ and $1^2=1$.
$=4\cdot 1+3\cdot 1-1+2$
Simplify.
$=4+3-1+2$
$=8$.
Substitute $x=2$.
$=4(2)^3+3(2)^2-(2)+2$
Use $2^3=8$ and $2^2=4$.
$=4\cdot 8+3\cdot 4-2+2$
Simplify.
$=32+12-2+2$
$=44$.
