Answer:

-2, 3

Step-by-step explanation:

For the product to be negative, exactly one of the two numbers must be negative. For the sum to be positive, the positive number must be larger than the absolute value of the negative number.

One such pair of numbers is -2 and 3.

Their product is -6; their sum is +1.

7 - 3[(n 3 + 8n) ÷ (-n) + 9n 2]

Answer:

$-24n^{2} +31$

Step-by-step explanation:

Given: $7-3[(n^{3} +8n)\div (-n)+9n^{2} ]$

Now simplifying expression using PEDMAS

First solving for small parenthesis.

taking common of n

= $7-3[n(n^{2} +8)\div (-n)+9n^{2} ]$

using law of indices, $\frac{x^{m} }{x^{n} } = x^{m-n}$

= $7-3[-(n^{2} +8)+9n^{2} ]$

Opening parenthesis

= $7-3[-n^{2} -8+9n^{2} ]$

= $7-3[ -8+8n^{2} ]$

Again using distributive property of multiplication

= $7+24-24n^{2}$

= $-24n^{2} +31$

Hence, the answer is $-24n^{2} +31$
