\frac{\left(x+1200\right)x}{x}-\frac{10000}{x}
To add or subtract expressions, expand them to make their denominators the same. Multiply x+1200 times \frac{x}{x}.
\frac{\left(x+1200\right)x-10000}{x}
Since \frac{\left(x+1200\right)x}{x} and \frac{10000}{x} have the same denominator, subtract them by subtracting their numerators.
\frac{x^{2}+1200x-10000}{x}
Do the multiplications in \left(x+1200\right)x-10000.
