$6 x^3-7 x^2+5 x-3 \text { from } 4-5 x+6 x^2-8 x^3$
$6 x^3-7 x^2+5 x-3 \text { from } 4-5 x+6 x^2-8 x^3$
✓
Answer
$ =4-5 x+6 x^2-8 x^3-\left(6 x^3-7 x^2+5 x-3\right) $
$ =4-5 x+6 x^2-8 x^3-6 x^3+7 x^2-5 x+3 $
$ =7-10 x+13 x^2-14 x^3 $
$ =-14 x^3+13 x^2-10 x+7$
$ =4-5 x+6 x^2-8 x^3-6 x^3+7 x^2-5 x+3 $
$ =7-10 x+13 x^2-14 x^3 $
$ =-14 x^3+13 x^2-10 x+7$
