Calculate or simplify the expression $$ (-4x^3+7x^2-8x+10)+(7x^3+10x^2-5x-2) $$.
Simplify the expression by following steps:
- step0: Solution:
  $$\left(-4x^{3}+7x^{2}-8x+10\right)+\left(7x^{3}+10x^{2}-5x-2\right)$$
- step1: Remove the parentheses:
  $$-4x^{3}+7x^{2}-8x+10+7x^{3}+10x^{2}-5x-2$$
- step2: Add the terms:
  $$3x^{3}+17x^{2}-13x+8$$
The result of the indicated operation is $$3x^{3}+17x^{2}-13x+8$$.

The degree of the polynomial is the highest power of the variable $$x$$. In this case, the highest power of $$x$$ is 3, so the degree of the polynomial is 3.
The degree of the polynomial is 3.
