Question
Find the following products:
$\left(x^3-2 x^2+5\right) \times(4 x-1)$
$\left(x^3-2 x^2+5\right) \times(4 x-1)$
✓
Answer
$=\left(x^3-2 x^2+5\right) \times 4 x+1\left(x^3-2 x^2+5\right) \times(-1)$
$=4 x^4-8 x^3+20 x-x^3+2 x^3-5$
$=4 x^4-9 x^3+2 x^2+20 x-5$
$=4 x^4-8 x^3+20 x-x^3+2 x^3-5$
$=4 x^4-9 x^3+2 x^2+20 x-5$
