\frac{x^{2}x}{x}+\frac{4000}{x}
To add or subtract expressions, expand them to make their denominators the same. Multiply x^{2} times \frac{x}{x}.
\frac{x^{2}x+4000}{x}
Since \frac{x^{2}x}{x} and \frac{4000}{x} have the same denominator, add them by adding their numerators.
\frac{x^{3}+4000}{x}
Do the multiplications in x^{2}x+4000.
