Evaluate (3x^{2}+x-8)(x^{3}+8)\,

Each term in the left parentheses should be multiplied by each term in the right parentheses, and they should all be added together.

(3x^{2})(x^{3})+(3x^{2})(8)+(x)(x^{3})+(x)(8)+(-8)(x^{3})+(-8)(8)\,

3x^{5}+24x^{2}+x^{4}+8x-8x^{3}-64\,

Arrange these terms by decreasing exponent of x.

3x^{5}+x^{4}-8x^{3}+24x^{2}+8x-64\,
