To expand the expression (x + 5)(2x² + x +3), we can use the distributive property and multiply each term of the first expression by each term of the second expression:

(x + 5)(2x² + x +3) = x * (2x² + x +3) + 5 * (2x² + x +3)

Expanding further:

= 2x³ + x² + 3x + 10x² + 5x + 15

Combining like terms:

= 2x³ + (x
