Question
Subtract:
$2 x^3-4 x^2+3 x+5$ from $4 x^3+x^2+x+6$
$2 x^3-4 x^2+3 x+5$ from $4 x^3+x^2+x+6$
✓
Answer
$ \left(4 x^3+x^2+x+6\right)-\left(2 x^3-4 x^2+3 x+5\right)$
$ =4 x^3+x^2+x+6-2 x^3+4 x^2-3 x-5 $
$ =4 x^3-2 x^3+x^2+4 x^2+x-3 x+6-5 \text { (Collecting like terms) } $
$ =2 x^3+5 x^2-2 x+1 $
$ =4 x^3+x^2+x+6-2 x^3+4 x^2-3 x-5 $
$ =4 x^3-2 x^3+x^2+4 x^2+x-3 x+6-5 \text { (Collecting like terms) } $
$ =2 x^3+5 x^2-2 x+1 $
