Answer 1

`\large \boldsymbol{} \longmapsto (5x^3+5x^2+5) -(6x^3-6x^2+8x-5 ) \\\\\\ \longmapsto5x^3+5x^2+5-6x^3+6x^2-8x+5 \\\\\\ \longmapsto 5x^3-6x^3+5x^2+6x^2-8x+5+5 \\\\\\ \longmapsto \boxed{ - x^3+11x^2-8x+10}`

Answer 2

`\\ \sf\longmapsto (5x^3+5x^2+5)-(6x^3-6x^2+8x-5)`

`\\ \sf\longmapsto 5x^3+5x^2+5-6x^3+6x^2-8x+5`

`\\ \sf\longmapsto 5x^3-6x^3+5x^2+6x^2-8x+5+5`

`\\ \sf\longmapsto -x^3+11x^2-8x+10`

`\\ \sf\longmapsto x^3-11x^2+8x-10`
