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\,
