Question

(4p²-p)+(5p-7)-(p²-7)​

Answer 1

Ответ:

3р²+4р

Объяснение:

(4р²-р) +(5р-7)-(р²-7)=4р²-р+5р-7-р²+7=3р²+4р

Answer 2

To simplify the expression (4p² - p) + (5p - 7) - (p² - 7), you can combine like terms and perform the operations:

1. Start by distributing the negative sign (-) to both terms inside the parentheses on the right side:

(4p² - p) + (5p - 7) - (p² - 7) = 4p² - p + 5p - 7 - p² + 7

2. Next, group like terms together:

(4p² - p - p²) + (5p + 7 - 7)

3. Combine like terms within each group:

(4p² - p² - p) + (5p + 0)

4. Subtract the polynomials in each group:

(3p² - p) + 5p

5. Finally, combine the two terms on the left side:

3p² - p + 5p = 3p² + 4p

So, the simplified expression is 3p² + 4p.
