Answer 1

`\bold{Answer}`

`\boxed{\bold{x^3-2x^2+11x+17}}`

`\bold{Explanation}`

• 
  `\bold{Solve: \ \left(x^3+8x+5\right)-\left(2x^2-3x-12\right)}`

`\bold{-------------------}`

• 
  `\bold{Remove \ Parenthesis \ (a) \ = \ a}`

`\bold{x^3+8x+5-\left(2x^2-3x-12\right)}`

• 
  `\bold{Simplify \ -\left(2x^2-3x-12\right): \ -2x^2+3x+12}`

`\bold{x^3+8x+5-2x^2+3x+12}`

• 
  `\bold{Simplify \ x^3+8x+5-2x^2+3x+12: \ x^3-2x^2+11x+17}`

`\bold{x^3-2x^2+11x+17}`

`\boxed{\bold{Eclipsed}}`

Answer 2

x^3+8x+5-2x^2+3x+12
