To simplify the expression \((6x^3 + 2x^2 - 5x - 14) - (-5x^3 + 7x^2 + 2x - 1)\), you need to distribute the negative sign across the second polynomial.
Step 1: Rewrite the expression by distributing the negative sign:
\[ (6x^3 + 2x^2 - 5x - 14) + (5x^3 - 7x^2 - 2x + 1) \]
Now, you can combine the two polynomials.
