A number n is multiplied by the sum of the product of the number and negative three and the square of the number

-3n²+n³

Step-by-step explanation:

Since the unknown number is n;

Product of the number and negative three is -3n

square of the number is n²

Taking their sum;

Sum = -3n + n²

Hence the sum of the product of the number and negative three and the square of the number is -3n+n²

If a number n is multiplied by the sum of the product of the number and negative three and the square of the number, hence the required function is;

f(n) = n(-3n + n²)

Expand

f(n) = -3n²+n³

This gives the required function

good luck!
