Final answer:
To subtract -4p²-9p+11 from p²-5p+4, distribute the negative sign to each term and combine like terms to simplify.
Step-by-step explanation:
To subtract -4p²-9p+11 from p²-5p+4, we need to distribute the negative sign to each term in -4p²-9p+11 to get -(-4p²)-(-9p)-11. Then, we can combine like terms by subtracting the coefficients of corresponding terms. Therefore, the subtraction becomes (p² + 4p²) + (-5p - (-9p)) + (4 - 11). Simplifying further, we get 5p² + 4 and that is the final result.
