To simplify \((6x^3 + 2x^2 - 5x - 14) - (-5x^3 + 7x^2 + 2x - 1)\), we first need to distribute the negative sign across the second polynomial. This means changing the signs of each term in the second polynomial.
Here’s how you would fill in the blanks:
1. The first polynomial is \(6x^3 + 2x^2 - 5x - 14\).
2. Now, we rewrite the second polynomial with the negative sign applied: \(- (-5x^3) = +5x^3\), \(- (7x^2) = -7x^2\), \(- (2x) = -2x\), and \(- (-1) = +1\).
So putting it all together in the step 1 format:
\(6x^3 + 2x^2 - 5x - 14 + 5x^3 - 7x^2 - 2x + 1\)
Thus, the filled-in blanks would be:
6x^3 **+** 2x^2 **-** 5x **-** 14 **+** 5x^3 **-** 7x^2 **-** 2x **+** 1
