Algebra-1

To expand the expression (3n + 2)(n² + n +3), we can use the distributive property and multiply each term of the first expression by each term of the second expression:

(3n + 2)(n² + n +3) = 3n * (n² + n +3) + 2 * (n² + n +3)

Expanding further:

= 3n³ + 3n² + 9n + 2n² + 2n + 6

Combining like terms:

= 3n³ + (3n
